You’re answer would be $28,000
So we can set x= width
2x+2 = length
so 2(x)+2(2x+2)= 76
so that will give us 2x+4x+4=76
6x=72
x=12
so 12 is width and 26 is length
The floor of the school has the shape of triangle.
So, the area of the floor is equal to the area of that triangle with base = 26 in, and height = 33 in.
The area of triangle = 0.5 * base * height
= 0.5 * 26 * 33 = 429 in²
∴ The area of the floor = 429 in²
Supplementary angles are angles that add up to 180 degrees
Answer = 180 - 142 = 38 degrees
