Area of triangle = 1/2 x base x height
Let the base be "b"
90 = 1/2 x 10 x b
90 = 5b
b = 18 ft
Base = 18 ft

Rectangular prism the two square on the end have 4 vertices each
The second one is bigger as the square is a even number with the negative whole
W is width
W+9 is length
W+W+9=54
2w=45
45/2
W=22.5
Width is 22.5 length is 31.5
