Question

Two sides of a parallel gram are in the ratio 5:6. If the permiter is 121cm find the length of its sides

Answer 1

Answer:

27.5,27.5,33,33

Step-by-step explanation:

so one side =5x and its opposite side = 5x

second side=6x and it's opposite side=6x

so 5x+5x+6x+6x=121

22x=121

x=121/22

x=5.5

so first side =5x=5*5.5=27.5cm

similar it's opposite side 5x=5*5.5=27.5cm

second side =6x =6*5.5=33cm

similarly its opposite side=6x=6*5.5=33cm

Answer 2

Answer:

one side of a parallelogram is 27.5 cm and the other side is 33 cm

Step-by-step explanation:

the ratio of two sides = 5:6

let the adjacent sides be 5x and 6x (we will take adjacent sides because in a parallelogram opposite sides are equal)

perimeter of the parallelogram=121

perimeter of a parallelogram=2(one side+other side)

121  =  2(5x+6x)

121  =  2 .  11x

121  =  22x

121/22 = x

5.5 = x

therefore,

                one side = 5x = 5*5.5 = 27.5cm

                other side = 6x =6*5.5 = 33cm
