Question

A rectangular skateboard park has an area of x^2+15x+56 what are the possible dimensions

Answer 1

For this case we have the following expression:
 x ^ 2 + 15x + 56
 We can factor this expression to find the possible dimensions of the rectangle.
 Factoring we have:
 (x + 7) (x + 8)
 Answer:
 the possible dimensions are:
 (x + 7) * (x + 8)
