Answer: 80, 1/12, 5/6
Step-by-step explanation:
I don't know if it is correct but here goes nothing 8*(d-3)
Let x = first number, and y = second number.
x + y = 40 (1)
x - y = 6.5 (2)
Rearrange (2)
y = x - 6.5 (3)
Sub (3) in (1)
x + (x - 6.5) = 40
2x - 6.5 = 40
2x = 33.5
x = 16.75 (4)
Sub (4) in (1)
16.75 + y =40
y = 23.25
x * y = 16.75 * 13.25 = 221.9375
The product is 221.9375
Perimeter = 2l+2w in this case. So 16+12, 28 feet is your answer!
