Answer: 20.5

Form your equation. The formula for perimeter is (2l)(2w) or l + l + w + w, where l = length and w = width.
(l - 5) + (l - 5) + (l) + (l) = 72

Simplify and solve your equation.
4l - 10 = 72
4l = 82
l = 20.5

Since l = length, length = 20.5 and width = 15.5

You can check your work, too:
20.5 + 20.5 + 15.5 + 15.5 = 72

Find the surface area and show work
Law Incorporation [45]

Answer: 1,270in^2

Step-by-step explanation:

The surface area of a rectangle can be calculated with:

Area_{rectangle}=lenght*width

The surface area of a trapezoid can be calculated with:

Area_{trapezoid}=\frac{height}{2}(Larger\ base+Smaller\ base)

Calculate the area of the base, wich is a rectangle:

A_{1}=(34in)(15in)=510in^2

There are two equal rectangles, therefore, multiply the area of any of them by 2:

A_{2}=2(15in)(13in)=390in^2

Calculate the area of the other rectangle:

A_{3}=(15in)(10in)=150in^2

There are two equal trapezoids, therefore, multiply the area of any of them by 2:

A_4=\frac{2(5in)}{2}(34in+10in)=220in^2

Therefore, the surface area will be the sum of all the areas calculated:

SA=A_1+A_2+A_3+A_4\\\\SA=510in^2+390in^2+150in^2+220in^2\\\\SA=1,270in^2

What is the lateral surface area of the pyramid?
Delicious77 [7]

Answer:

1,536 square centimeters

Step-by-step explanation:

The formula for the Lateral surface area of the pyramid =

1/2 × perimeter of the square base × slant height

Square base = 32cm

Slant height = 24cm

Perimeter of the square base = (4 × length of the square base side)

4 × 32cm = 128cm

Lateral Surface Area = 1/2 × 128cm × 24cm

= 1,536 square centimeters
