Question

The length of a rectangle is 20 meters and the width is 4 meters. What is the perimeter of the rectangle? Do not include units in your answer.

Answer 1

Answer:

$\boxed {\boxed {\sf 48 \ meters }}$

Step-by-step explanation:

The perimeter is the sum of the side lengths.

A rectangle has 4 sides: 2 lengths and 2 widths, so the perimeter formula is

$p= 2l+2w$

The length is 20 meters and the width is 4 meters.

$p= 2(20 \ m )+ 2(4 \ m )$

Multiply.

$p= 40 \ m + 8 \ m$

Add.

$p= 48 m$

The perimeter of the rectangle is 48 meters.
