Question

The perimeter of a rectangle is 2.640 km the length and breadth of its sides are in the ratio 5:3. Find the length and breadth of the rectangle.​

Answer 1

Step-by-step explanation:

2 × 8x = 2.64

200×8x = 264

50× 8x = 66

25× 8x = 33

x = 33/200

l = 5× 33/200= 33/40

b = 3×33/200

b = 99/200

Answer 2

length=0.825km

breadth=0.486km

Step-by-step explanation:

2.640km=2(5x+3x)

2.640km=2*8x

2.640km/2=8x

1.320=8x

1.320/8=x

0.165=x

L=0.165*5=0.825km

B=0.165*3=0.489
