Answer:
31.25 in²
Step-by-step explanation:
Surface area of triangular pyramid
Perimeter, P = 4s = 4 * 2.5 = 10 inches
Lateral surface area = 0.5 * P * height = 0.5 * 10 * 5 = 25 inch²
The base area = s² = 2.5² = 6.25 inch²
Hence, surface are ao triangular pyramid ;
Lateral surface area + base area
= 25 inches + 6.25 inch²
= 31.25 in²

Step-by-step explanation:
Area of one side of the shed
5*4=20
she painted 4 sides so 20*4 =80
Triangle that is part of the pyramid as the roof of the shed has a side of 5. Using the Pythagorean theorem,
we need to find the square root of 18.75 to find the height of the triangle which is
that is the height
(base x height) /2 is the formula for a right triangle. there are 2 of these right triangles per side of the roof. so we need to multiply the numbers by 8
this number gives us 43.30127019
we can finally add that number to 80 to get the total surface area Zoe painted which is 123.3012702
