Question

The perimeter of the rectangular room is 160m .their length and breadth are in the ratio 3:5 .what is the area of the room?

Answer 1

Answer:

1000 sq. m

Step-by-step explanation:

Let the length and the breadth of the rectangle be 3x and 5x.

We know that,

Perimeter of the rectangle= 2( Length+Breadth)

So, perimeter of the given rectangle= 2(3x+5x)

A/Q,

2(3x+5x) = 160

2×8x= 160

16x =160

x=160/16

x=10

Therefore, x=10

And, length=2x=2×10=20 m

breadth=5x=5×10=50 m

Hence, Area of the rectangle=Length×Breadth=(20×50) sq. m=1000 sq. m
