Answer 1

Answer:

75 in²

Step-by-step explanation:

From the diagram, you can see that the shape is made up of a square and 4 triangles. (We know it's a square as the width = length).

First, find the area of the square.

Area of a square = width x length = 5 x 5 = 25 in²

All the triangles are the same, so we need to find the area of one of the triangle and multiply it by 4.

Area of a triangle = $\frac{1}{2}$ x base x height = $\frac{1}{2}$ x 5 x 5 = 12.5 in²

So total area of 4 of these triangles = 4 x 12.5 = 50 in²

Therefore the total surface area = 25 + 50 = 75 in²
