Question

two sides of parallelogram are in the ratio7:4 if its perimeter is 88cm find the lenth of its sides

Answer 1

Answer:

as opposite sides are equal

let sides be 7x, 7x , 4x and 4x

perimeter=88cm

= 7x+7x+4x+4x

= 22x =88cm

so x= 88/22

x= 4 CM

now 7x = 7*4=28 CM

4x= 4*4= 16cm

so sides are 16cm , 16 CM, 28 CM 28cm

Answer 2

Answer:

Let one side of parallelogram is 7x and other side is 4x

opposite sides must be 7xand 4x bcoz it's opposite sides are same.

perimeter=sum of all sides

88 = 7x+4x+7x+4x

88= 22x

88/22= X

X=4

So,sides of parallelogram are 28,16,28,16
