In two similar triangles, the ratio of their areas is the square of the ratio of their sides. Let's assume LMN and FGH are similar triangles. The ratio of the areas of LMN to FGH is 18 to 24, or 3 to 4 or 0.75. We would then take the square root of 0.75 to get the ratio of the sides. I get 0.866. The reason it is the square is the area of a triangle is base times height divided by 2, and the base and height and sides of similar triangles are proportional.

Good luck.

Find the scaling ratio

Perimeter of first pentagon is 12*5=60 cm

Scale factor (2nd/first)=140/60 =7/3

**Ratio of areas varies as the square of the scale factor for the lengths**

Area of second / area of first =(7/3)^2 =49/9

Area of second pentagon =**248 *(49/9) cm^2**

Finish the calculation.

The two pentagons are similar. If k is the scale factor for the lengths, the ratio of the areas is k^2.

Pent 1 side =12 cm

Pent 2 side =140/5 =28 cm

Scale factor (larger over smaller) is k=28/12=7/3

Area of Pent_2= (49/9)*Area of Pent_1

Your answer should be C.

Pent 1 side =12 cm

Pent 2 side =140/5 =28 cm

Scale factor (larger over smaller) is k=28/12=7/3

Area of Pent_2= (49/9)*Area of Pent_1

Your answer should be C.

You need to calculate the slant height of the pyramid for the formula of the lateral area. You should find a value of** (1/2)*SQRT(203) **or about 7.1239 cm

You need to calculate the altitude (height) of the pyramid from the apex (summit) to the center of the base triangle (center of inscribed circle, barycenter, orthocenter). The hypotenuse of such triangle is the slant height. One leg is the altitude (to be found),**the measure of the second leg is (1/3) the altitude** **of the equilateral triangle** that forms the base. You should find (1/3) m MH= (1/3)* **(11/2)*SQRT(3)**

1. Calculate the area of the base (use a formula for the equilateral triangle or the general formula for a triangle: you have its height MH ).

2. Lateral area = 3 times the area of triangle Triangle ECD (in yellow above).

3. Total area = area of base + lateral area.

4. Volume= (1/3)(Area of base)* (height of pyramid)

Hypotenuse being 10 makes the other sides of the triangle 5radical2. Area of a triangle is 1/2*b*h, for an isosceles triangle, it will be 1/2*b*b.

1/2*(5rad2)*(5rad2) 1/2*5*5*rad2*rad2 1/2*25*2 25 cm^2

1/2*(5rad2)*(5rad2) 1/2*5*5*rad2*rad2 1/2*25*2 25 cm^2

In right triangle we are making 90 degree angle triangle, we can have problem for finding hypotenuse or finding sin or cos values of the side of the triangle.
For ex,Find out the hypotenuse,sin and cos value of the right triangle with base 4 cm and perpendicular 3 cm
Solution:Hypotenuse = SQRT(4^2 + 3^2)
=SQRT(4*4 + 3*3)
=SQRT(16+9)=SQRT(25)=5 cm
For right triangle,
sin(x)=3/5=0.6
cos(x)=4/5 =0.8

If the distance is 2 cm longer than the short side of a right triangle then the lengths could then be assumed as:

Right triangle A/B = 3 cm

A/C = 1 cm

B/C = 3 cm

Right triangle A/B = 3 cm

A/C = 1 cm

B/C = 3 cm
