Question

the perimeter of the rectangle is 320C.M ,If the ratio of the length of the sides is 3.5,find the length and breadth of the rectangle.​

Answer 1

Answer:

Hey Friend,

Let x be the common factor

Ratio=3x:5x

Perimeter= 2(l+b)

320= 2(3x+5x)

320/2= 8x

8x= 160

x= 20

Therefore,

Length=3x=3*20=60

Breadth=5x=5*20=100

Hope it helps.... :)

Answer 2

Answer:

P=2*l+2*b

320=2*3.5+2*b

320=7+2b

2b=320-7

b=313/2

b=156.5
