Question

The area of a rectangular hall is 144 square M if its length is 4 times its breadth what is the length and breadth of the hall?

Answer 1

Let the breadth be x m.Then length =4x,Now area of rectangular hall=l×b=4x×x4x2,144=4x2=x2=144/4=36,hence ,x,=6Then,Length=24m and breadth =6m

Here is your answer.

Area of rectangular hall = 144 ${m}^{2}$

Let the breadth be x.

So, the length is 4x.

Area of rectangle = l × b

144 = 4x × x

$144 = 4 {x}^{2}\\ {x}^{2} = \frac{144}{4}\\ {x}^{2} = 36\\ x = \sqrt{36}\\ \\ x = 6$

THEREFORE, Breadth is 6 cm and Length is 4 × x.

= 24 cm
