Answer:
Below :)
Step-by-step explanation:
1) 5^2 = 25
2) 12^2 = 144
3) 9^2 = 81
4) 15^2 = 225
5) 8^2 = 64
6) 7^2 = 49
7) 20^2 = 400
8) 13^2 = 169
9) 30^2 = 900
10) 25^2 = 625
The surface area is the area of the outside of a 3D shape for example, let’s say you have a cube, a cube has 6 sides, so you have to find the area of each side and then add it up, since it’s a cube you would technically have to find the area of one side and then just multiply it by 6, that would be the easiest way to do it
Hope I helped!
A trapezoid is a quadrilateral because it has 4 sides. A quadrilateral is not always a trapezoid because a quadrilateral can be any shape as long as it has four sides.
I may not make sense but I hoped this helped! :)
