Question

The sides of a rectangle are in the ratio of 3:5. Find its sides if the perimeter is 80

Answer 1

Answer:

30,50

Step-by-step explanation:

let 3:5 be 3x,5x

now,

3x+5x=80

8x=80

x=10

so,

1st side=3×10=30

2nd side=5×10=50

Answer 2

Answer:

Step-by-step explanation:

2(3x + 5x)= 80

2* 8x=80

16x=80

x=80/16

x=5

side1= 3*5=15

side 2 =5*5= 25
