You know the area, so you can use the area formula A = 1/2(a+b) (a and b being the parallel sides AB and CD) 
So, set 32.5 = 1/2 (AB +CD)
substitute --> 32.5 = 1/2( x+(x+1) )
simplify --> 32.5 = (2x+1)/2
simplify again --> 65 = 2x +1 --> 64 =2x --> 32 =x
Now that you have x, you can substitute it into the formula for your height (x-1) to get 31

Can someone help me please
Masja [62]

Answer:

51ft, 17ft, 39ft

Step-by-step explanation:

longest = x

2nd = \frac{1}{3}x

3rd = x - 12

P = 107

a + b + c = Perimeter

x + \frac{1}{3}x + x - 12 = 107

\frac{7}{3}x -12 = 107

\frac{7}{3}x = 119

x = 51

\frac{1}{3}x = 17

x - 12 = 39
