Question

the perimetre of a rectangle is 2.640km the length and breadth of its side are in the ratio 5:3 find the length and breadth of this rectangle​

Answer 1

Answer:

Step-by-step explanation:

Perimeter = 2.640km

In m = 2.640×1000

= 2640 m

Now ratio of sides is 5:3

Let side be x then length be 5x and breath be 3x

APQ,

PERIMETER =2(L+B)

2640 =2(5x+3x)

2640=2×8x

2640=16x

X=165m

Now , length is 5x then length will be

5×165=825m

Breath is 3x then it will be

3×165=495m

Therefore lengtg is 825m and breath is 495m

Answer 2

Step-by-step explanation:

Perimeter = 2.640km

In m = 2.640×1000

= 2640 m

Now ratio of sides is 5:3

Let side be x then length be 5x and breath

be 3x

APQ,

PERIMETER =2(L+B)

2640=2(5x+3x)

2640=2x8x

2640=16x

X=165m

Now, length is 5x then length will be

5×165=825m

Breath is 3x then it will be

3x165-495m

Therefore lengtg is 825m and breath is

495m
