Question

Write and simplify expressions for the area and the perimeter of a rectangle.

The rectangle has a width of 5 and a length of x+2.

Answer 1

The expression for the perimeter of the rectangle is 14+2x

The expression for the area of rectangle is 5x+10

Step-by-step explanation:

Given

width (b) = 5

length (l) = x+2

We know,

Perimeter of a rectangle = 2 (l+b)

The expression for the perimeter of the rectangle becomes 14+2x

Area of rectangle = lXb

The expression for the area of rectangle becomes 5x+10

Therefore,

The expression for the perimeter of the rectangle is 14+2x

The expression for the area of rectangle is 5x+10
