Question

Find the perimeter of a rectangle with width 20.0 inches and length 21.8 inches. Round your answer to the nearest tenth.

Answer 1

Given:

Length of the rectangle is 21.8 inches.

Width of the rectangle is 20.0 inches.

To find the perimeter of a rectangle:

Using the formula, we get

$\begin{gathered} P=2(l+w) \\ =2(21.8+20.0) \\ =2(41.8) \\ =83.6\text{ inches} \end{gathered}$

Hence, the perimeter of the rectangle is 83.6 inches.
