Question

The perimeter of a parallelogram is 180cm. One of it side is greater than the other by 30 cm. Find the length of the sides of the parallelogram​

Answer 1

Answer:

Step-by-step explanation:

1st side be x

2nd side = x+30

perimeter of ||gm = 2x + 2(x+30)

180=2x+2x+60

120=4x

30=x

1st side is 30cm

2nd side is 60cm

Answer 2

Answer:

Length = 60

Width = 30

60 + 60 + 30 + 30 = 180

Step-by-step explanation:

Let a = width of parallelogram

Let a+30 = length of parallelogram

a + a + a +30 + a +30 = 180

4a + 60 = 180

4a = 120

a = 30 cm

Length = 60

Width = 30

60 + 60 + 30 + 30 = 180

Checking:

2a + 2(a+30) = 180

2(30) + 2(30+30) = 180

30 + 2(60) = 180

30 + 120 = 180

180 = 180
