Question

The area of a rectangle is $117m^2$. Its width is $9m$. Calculate its length.

Answer 1

Step 1: We have

Area of rectangle$=117m^2$

And the width of rectangle $b=9m$

Let the length of the rectangle be $l$

Step 2: Finding length

Area of rectangle $=length\times width$

$117m^2=l\times b$

so,

$l\times b=117m^2$

$l\times 9m=117m^2$

So, $l=\frac{117m^2}{9m}$

$l=13m$

Hence, the length of the rectangle$=13m$
