Question

The area of a rectangle is 117 cm2 and its breadth is 9.75 cm, find the length.​

Answer 1

Answer :-

Formula used :-

Area of rectangle = length × breadth

Given :-

area of rectangle = 117cm^2

breadth = 9.75 cm

Now , using formula

$l \: \times b \: = a$

$l \: \times 9.75 = 117$

$l \: = \frac{117}{9.75}$

$l \: = \frac{39 \times 3}{3.25 \times 3}$

$l \: = \frac{39}{3.25}$

$l \: = \frac{3900}{325}$

$l \: = 12$

So , the length of rectangle is 12 cm
