Question

I need answer for this +explanation i don't get it​

Answer 1

Answer: 95 ft²

Explanation:

To solve for the surface area, we will find the area of all the sides and then add them together. We see that we have a square as the base and 4 congruent triangles.

For the square:

A = LW

A = (5 ft)(5 ft)

A = 25 ft²

For one triangle:

A =
`(BH)/(2)`

A =
`((5\;ft)(7\;ft))/(2)`

A = 17.5 ft²

For all four triangles:

A = 17.5 ft² * 4 = 70 ft²

Total surface area by adding the triangles and square together:

70 ft² + 25 ft² = 95 ft²
