GEOMETRY The rectangle has a perimeter of P centimeters. Which equation could be used to find the length l of the rectangle?

A. P=2.4l

B. P=2.4+2l

C.P=4.8+l

D.P=4.8+2l

Short Answer

Expert verified

Option D.P=4.8+2l is the correct choice.

Step by step solution

01

Step 1. Use the definition of a rectangle’s perimeter.

For a rectangle perimeter is the sum of the lengths of all its sides, thus we add two lengths and two breadths to find the perimeter of the rectangle.

02

Step 2. Find the perimeter.

We are given that the length of a rectangle is l and its width is 2.4cm thus its perimeter can be calculated as:

P=2length+breadthP=2l+2.4P=2l+4.8

Thus, Option D. P=2l+4.8is the correct choice.
