### All three sides of a triangle are equal in length of one side is 2x+5 and one side is 4x-3 find the perimeter of the triangle

If all sides are equal then 2x + 5 = 4x - 3
2x = 8
x = 4

so the perimeter is 3 times either expression above
3 * (8 + 5) = 39

### The base of an isosceles triangle is 2 more than one of the equal sides. If the perimeter is 41 find each side of the triangle

41-2 = 39/3 = 13: now all three sides are equal. Add 2 inches to the base 13+2=15. Equal sides are 13 each and base is 15. 13+13+15=41

### 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
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.
