<h3>Answer: 119 square meters</h3>

===========================================================

Explanation:

The figure is an unfolded version of a pyramid, so it's placed as flat as possible.

The square in the middle has area of 7*7 = 49 square meters. This is the base or floor of the pyramid.

Each triangle has area of base*height/2 = 7*5/2 = 35/2 = 17.5 square meters. Four such identical triangles combine to an area of 4*17.5 = 70 square meters. This is the lateral surface area, which is everything but the base.

So the total surface area is

BaseArea + LateralSurfaceArea = 49+70 = 119 square meters

What is the solution to the equation 7(a – 10) = 13 – 2(2a 3)?

geniusboy [140]

7(a - 10) = 13 - 2(2a + 3)
7a - 70 = 13 - 4a - 6 = 7 - 4a
7a + 4a = 7 + 70
11a = 77
a = 77/11 = 7
a = 7.
