Answer:
300
Step-by-step explanation:
As you probably know the perimeter of a rectangle is given by the formula 2l + 2w where the length and width are represented by the letters l and w .
In our case,
l = w + 5 ( since the problem states that the length is 5 more than the width)
70 = 2 (w+5) + 2w
70 = 2w + 10 + 2w
4w = 60
w = 15
l = 20
Our length is going to be 20 ft and our width 15 ft
To solve the area, we will multiply 15 and 20.
15x20 is 300
