Three more than nine times a number is at least five times the number.
Answer:
it's a trapezoid
Step-by-step explanation:
((major base + minor base) x height) / 2
((7+5)x8) / 2 = 52
C I took the tests on eg today
To begin, if the base is a square, then each side of this square would be 3 ft. there are 4 traingles, and the area of a triangle is 1/2bh, the height being the slant height and the base being one side of the square. Therefore, the surface area is 4(1/2)(3)(8)+9=57 ft^2
