Answer:
64 inches squared
Explanation:
The formula for the area of a triangle is 0.5 x base x height. The base of the triangles is 4, and the height is 6. If we fill in the formula, 0.5 x 4 x 6, we get 12 inches squared. There are four triangles, so the total area if the triangles is 12 x 4 or 48 inches squared.
That just leaves the square, which we are given the side length of. 4 x 4 is 16 inches squared.
To find the total surface area of the object, add the value of the triangles and square.
48 + 16 = 64 inches squared
