The length of the diagonal and the shorter base are 17. 24 feet and 18. 7 feet long respectively. 
<h3>How to determine the length</h3>
The cosine rule is given as;

c = length of the diagonal
a = base length = 22 feet
b = 7 feet

Mr. drove 3 times more then Mrs.. ok
so how far Mrs. drove will be X
and Mr. will be Y
but we know that Mr. drove 3 times more then Mrs therefor 
Y= 3X
and the Sum = 3,200
3,200=X+Y
3,200= X+(3X)
3,200=4X
div both by 4
800=X
now we know how far Mrs drove now to find Mr.
again "Mr. drove 3 times more then Mrs"
800 * 3 = 2,400
        
             
        
        
        
Answer: x = 7 and y = -17
Step-by-step explanation:
Opposite sides of parallelograms are equal.
-5y + 3 = 88
-5y = 85
y = -17
10x - 7 = 63
10x = 70
x = 7
