Question

The perimeter of the square is 140 cm. Find the length of each side.​

Answer 1

Step-by-step explanation:

The perimeter of a parallelogram is 140 cm. If one of the sides is longer than the other by 10 cm.

Let smaller side (a) =x then longer side (b)=x+10

Perimeter =2(a+b)=2(x+x+10)=140

=> x=30

Smaller side =30cm Larger side =30+10=40 cm

Answer 2

Answer:

2(x+x+10) =140

2(2x+10) =140

2x+10=702x=70-10

2x=60

x=30

first side x=30cm

second side=x+10=40cm
