Question

A rectangle has length 7 inches and width 3 inches.

Answer 1

Answer:

The area of rectangle is 21 in^2

Step-by-step explanation:

we know that

The area of rectangle is equal to

$A=LW$

where

L is the length

W is the width

In this problem we have

$L=7\ in$

$W=3\ in$

substitute

$A=(7)(3)=21\ in^2$

The draw in the attached figure

therefore

The area of rectangle is 21 in^2
