In a rectangle, one side is 8 m larger than the other, find the area of the rectangle if its perimeter is 28 m.

The smaller of the sides of the rectangle is designated by the conditional variable “Y”.
This means that the largest of the sides will be equal to Y + 8 meters.
The next step is to compose the equation: (Y + Y + 8) x 2 = 28.
When we solve the resulting equation, we have 2Y + 8 = 14 or 2Y = 6 or Y = 6/2 = 3 meters.
Therefore, the large side of the rectangle will be 3 + 8 = 11 meters.
This means that the area of the rectangle is 3 x 11 = 33 m ^ 2.
Answer: 33 m ^ 2.
