Question

6. The measures of two adjacent sides of a rectangle are in the ratio 5 : 3. If the perimeter of the rectangle
is 80 m, find its length and breadth.​

Answer 1

Answer:

Length=25m

Breadth=15m

Step-by-step explanation:

let x be the common multiple of 3:5

Therefore,5x and 3x

perimeter of rectangle=2 (l+b)

80 = 2 (5x + 3x)

80 = 2 (8x)

80÷2 = 8x

40 = 8x

40÷8 = x

5 = x

Therefore,

length = 5x = 5×5 = 25m

Breadth = 3x = 3×5 = 15m

Answer 2

Step-by-step explanation:

let two adjacent sides of a rectangle be 5x and 3x

perimeter of the rectangle=80m

perimeter of rectangle=2(l+b)

80=2(5x+3x)

80÷2=8x

40=8x

x=40/8=5

length=5x=5*5=25

breadth=3x=3*5=15
