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

Answer:

Step-by-step explanation:

Let the breadth be x

Length = 4x

Area of wall =l*b

=4x*x

ATQ

4x*x=144

x²=144/4

x²=36

x=6

Breadth=x=6m

Length=4x=24m

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
