Question

What is the perimeter of the rectangle? Write your answer in simplified form.

Answer 1

Explanation:

The perimeter of the given rectangle is 2[5x+1] units or 10x+2 units.

The perimeter, P, of a rectangle is given as 2(l+b), where l=length of the rectangle, in this case, it is 3x; While b=breadth of the rectangle, and in this case, it is 2x+1. Therefore, the Perimeter, P, of the given rectangle equals 2[3x+(2x+1)] = 2[5x+1] units or 10x+2 units.

Answer 2

We have to express the perimeter of the rectangle.

The perimeter is the sum of the lengths of the sides, so we can write:
