Find the perimeter of the rectangle ABCD The rectangle consists of two halves AEDF where AE = 3cm.

Find the perimeter of the rectangle ABCD The rectangle consists of two halves AEDF where AE = 3cm. And EBFC where EB = 2cm the area of the second 8cm squared, you need to find the perimeter.

First, we find the side of the rectangle AB:
AB = AE + EB = 3 + 2 = 5 cm;
We know the area of the rectangle EBCF, find the side BC:
BC = area / BE = 8/2 = 4 cm.
We know the two sides of our rectangle, the other two sides are the same.
Perimeter ABCD = 4 + 5 + 4 + 5 = 18 cm.
