Answer:c=127.3ft
Step-by-step explanation:Divide the square into two on the line between 1st and 3rd base, you now have two right triangles, pick one. The triangle has two legs and a hypotenuse, the length of the hypotenuse is the distance you need. The legs are 90ft long and you need to use the Pythagorean theorem. 90 squared plus 90 squared equals c squared, so 8100+8100=c^2, 16200=c^2, c=127.27922061
Since lateral surface of an object is the area of all the sides of the object, except the area of its base and top.
It is:
7 * 3 = 21
21 * 2 = 42
12 * 3 = 36
36 * 2 = 42
42 + 42 = 84 in2
and there goes your answer.
A: 84 in2.
