Question

A rectangular flower bed is enlarged so that its area increases by 24 ft². The enlarged flower bed is a rectangle and its area is x2+11x+24 ft².
What expressions represent the dimensions of the flower bed before the increase?

Answer 1

If a is the original area we can say that:

a+24=x^2+11x+24

a=x^2+11x  now we have the original area which when factored gives you the dimension of the original flower bed

x(x+11)

So the dimensions were x by x+11
