Question

the perimeter of a rectangle is 2.64km
and the ratio of its length and breadth is 5:3. find the length and breadth of the rectangle
​

Answer 1

Answer:

length=825m or 0.825km

Breadth=485m or 0.485km

Step-by-step explanation:

Ratio of length and breadth=5:3

Taking x as common multiple,

length=5x

breadth=3x

1km=1000m

∴2.64km=2640m

Perimeter of rectangle=2(l+b)

2640=2(5x+3x)

2640=2(8x)

2640=16x

2640/16=x

165m=x

length=5x=165×5

=825m or 0.825km

Breadth=3x=3×165

=485m or 0.485km
