Question

The length of a room is 6.25 feet longer than the width, x. Write a expression that represents the perimeter of the room

Answer 1

P=4x+12.5

Explanation:

Step one:

given data

width W= x

Length L= (x+6.25)

We know that the perimeter of a rectangle is expressed as

P=2L+2W

P=2(x+6.25)+2(x)

P=2x+12.5+2x

collect like terms

P=2x+2x+12.5

P=4x+12.5

Hence the expression for the Perimeter is

P=4x+12.5
