Let x = the short side. Then the long side is the short side plus 6 meters
now we have 2 sides that are x meters long, add those together gives us 2x for the length
of both short sides

The length of the long side is x + 6 for one side and x + 6 for the other side. Added together we have x + 6 + x + 6 = 2x + 12

Adding the 4 sides together we get 2x ( the 2 short sides) + 2x + 12 (the long sides) we get 4x + 12 = the perimeter or 628. 4x + 12 = 628. Subtract 12 from both sides of the equation leaves 4x = 616. divide both sides by 4 leaves x = 154 So the width is 154 meters and the length is 160 meters.

Hope this helps

Good luck Loringh

A rectangular computer chip is 7/8 inch long and 5/16 ich wid. An insulating strip must be put around all sides of the chip. hat is the length of the strip using this formula. P=21+2w


One dimension is the length lower case l, the other is the width w. The perimeter for this rectangle is P= 2*l+2*w=2*(l+w)=2*(7/8 +5/16)
=2*(14/16+5/16)= 2*(19/16)=19/8 inches.

The perimeter of a rectangle is 600 yards. what are the dimensions of the rectangle if the length is 20 yards more then the width


160 by 140

The perimeter is 600, so 2w+2l=600 where w is the width and l is the length.
Divide both sides by 2: w+l=300
The length is 20 more than the width: l=w+20
Substituting in the previous equation: w+(w+20)=300
Collecting terms: 2w+20=300
Subtract 20 from both sides: 2w=280
Divide by 2: w=140
Thus the width is 140. Substituting into the equation for length: l=140+20
Simplifying: l=160
The width is 140 and the length is 160

P=228 width is 24 ft less than the length


Say length is x.
Width is x-24.
Perimeter is length plus width plus length plus width = 228.
x + (x-24) + x + (x-24) = 228
4x-48 = 228
4x=276
x=69
length = 69
width = 69-24= 45

check: 45 + 69 + 45 + 69 = 228

The volume of a rectangular prism is 2,058 cubic cm. The length of the prism is 3 times the width. The height is twice the width. Find the length of the prism


Right Rectangular prism, Length L, width W, Height H
Volume=2058 cm^3=L*W*H
However
L=3W, and H=2W
(3W)*W*(2W)=6 W^3=2058
W^3=(2058/6)=343
W=Cube root of 343=(343)^(1/3)=7 cm
L=3*7=21 cm
H=2*7=14 cm

What is the perimeter of a 1 x 3 rectangle?


Rectangle has two pairs of equal sides.
L=length=3 units
w=width =1 unit
Perimeter = sum of the measures of all sides.
2 sides with measure L: sum of lengths=2*L
2 sides with measure w: sum of widths=2*w
Perimeter = 2L+2w=2(L+w)=2(1+3)=8 units.

Surface area of a rectangular prism whose length is 7 cm.,width is 4 cm., and thickness is 5 cm.?


Since the 'base' and 'top' of any prism have the same shape, the surface area can be found by
  • surface area of prism = 2 * area of base + perimeter of base * H
So for the rectangular prism in your example..
  • surface area = 2LW + 2(L+W)H
  • = 2 * 7 * 4 + 2*(7+4)*5
  • = 56 + 2 * 11 * 5
  • = 56 +110
  • = 166 sq cm

A rectan Dear Madam Please look at the math questions below. Please help me solve the questions Question 1 : A rectangular tablecloth is 2.5 m long. Trim is to be sewn around the perimeter of the cloth...


1. Well this one is pretty simple. Since you are not supposed to trim the length trim the width instead.
to make the perimeter 0.4 m shorter cut the cloth by 0.2 m width the picture will make it clear.

2. let the length of rectangle be x cm
and breadth = 20 cm
now original perimeter = 2(x+20) cm


new length = x-30 cm
breadth remains same = 20 cm
new perimeter = 2(x-30+20) cm = 2(x-10) cm

According to question

new perimeter = old perimeter /2
2(x-10) = 2(x+20) /2
2x -20 = x + 20
x = 40 cm


hence length of longer side 40 cm.

What is rectangular prism?


Hello
Rectangular Prism/Cuboid Definition:
A Rectangular Prism/Cuboid is a solid figure bounded by six rectangular faces, a rectangular box. All angles are right angles, and opposite faces of a cuboid are equal. It is also a right rectangular prism.

Rectangular Prism/Cuboid Formula:
Area of Base(A) = l * w
Perimeter of Base(P) = 2l + 2w
Surface Area of Prism = 2(lw) + (2l + 2w)h = 2A + Ph
Volume of Prism = lwh = Ah
Diagonal of Prism = Sqrt(l² + w² + h²)
where
l = length, w = width, h = height

Hope this helps, if so do rate the solution
