Question

Perimeter of a parallelogram is 180cm. One of its sides is greater than the other side by 30cm. Find the lengths of all sides.​

Answer 1

Answer:

length of first side = 60 cm, other side=30 cm

Step-by-step explanation:

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

perimeter=180 degrees , length of other side = x, length of first side =x+30

therefore 2(x+30+x)=180

2x+60+2x=180

4x=180-60

4x=120

x=120/4

x=30

length of first side=30+30=60cm

length of other side=30cm
