Question

7). The perimeter of a parallelogram is 68m. If the ratio of two sides of parallelogram is 7:10, find
lengths of sides of parallelogram.​

Answer 1

Step-by-step explanation:

Let the adjacent sides of parallelogram be x and y

• 2x+2y=68
• x+ y=34 ........(1)

x/y=7/10

• x=7y/10=0.7y.......(2)

substituting 2 in 1

we get 0.7y+y=34

• 1.7y=34
• y=20

then from 1

x =14
