Question

The length of room is twice its breadth if the area is 242 square meters then find out it's breadth

Answer 1

Answer:  11 m

Step-by-step explanation:

Length of the room (L) = 2 x breadth of the room (B)

L= 2 x B

Given that the area = 242 sq. m

L x B = 242

2 x B x B = 242

2 x B² = 242

B² = 121

B = 11 m

Answer 2

Let, the breadth be, 'x'

Length = (x*2)

            = 2x

By condition,

(2x*x) = 242

or, 2x² = 242

or, x² = 242/2

or, x² = 121

or, x = √121

or, x = 11

So, the breadth is 11 m.

(Ans): 11 m.
