Question

The length of a rectangle is 5 units longer than its width, w. Select the expression that represents the perimeter of the rectangle.

Answer 1

Answer: The expression that represents the perimeter of the rectangle is given as

Perimeter= 4x +10

Explanation:

Perimeter= 2l+2w =2( l+w)

Let the width be =x

And Length=x+5

So that the Perimeter =2l+2w becomes

Perimeter =2x +2(x+5)

Perimeter =2x+2x+10

Perimeter= 4x +10
