Find the surface area of the square pyramid. Round your answer to the nearest tenth. The base has a side length of 4.6 yds and then vertex of a lateral side is 60%.

A.

Step-by-step explanation:

The area of the base is 21.16

You have a 30°60°90° triangle on the sides, and the leg opposite to 30° is 2.3

The height of the triangle is 2.3√3

The area of one of the triangles is 2.3√3 * 2.3 =  5.29√3

The area of all four triangles is 21.16√3

21.16√3 ≈ 36.7

Hope I'm not wrong.

Correct answer is 57.8 yd², I just took the test

5+2x=a
