Question

4. The length and breadth of rectangle are in the ratio 3 : 2. If the area of the rectangle is726 m



2

, find its perimete

Answer 1

Answer:

110m

Step-by-step explanation:

Let the length be 3x and breadth be 2x

According to question:

3x*2x=726

6x²=726

x²=121

x=11m

∴length=3x=3*11m=33m

breadth=2x=2*11m=22m

∴perimeter=2(length+ breadth)

=2(33+22)m

=2*55m

=110m

Answer 2

Answer:

110m

Step-by-step explanation:

The length and breadth of rectangle are in the ratio 3 : 2

Let  the length and breadth be 3x and 2x respectively

Given: area=726m²

==>length×breadth=726

==>3x × 2x=726

==>6x²=726

==>x²=726/6=121

==>x=11m

THerefore,

length=11×3=33m

breadth=11×2=22m

Perimeter=2(length+breadth)

               =2(33 + 22)=2(55)=110m
