Question

Two sides of parallogram are in the ratio 7:3 if iys perimeter is 80 find the lenght of each side

Answer 1

Answer:

Solutions:

let the sides of the parallelogram be 7x and 3x

so ,

perimeter = 2(l+b)

80 = 2(7x+3x)

80= 2× 10x

20x= 80

x = 80÷20

x =4

so the sides are 7×4 unit

and 3×4 unit so ,

the sides are 28 unit,12 unit
