Question

the measure of two adjacent side of a rectangle are in the ratio 5 ratio 3 if the perimeter of the rectangle is 80 m find length and breadth

Answer 1

Answer:

Step-by-step explanation:

Let x be the common multiple of 5:3

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

Let length=5x
breadth=3x
Perimeter=80m
2(l+b)=80
2(5x+3x)=80
8x=40
x=5m
So, length=5x=5(5)=25m
and breadth=3x=3(5)=15m.
