Question

the perimeter of a parallelogram is 140 CM if one of the side is longer than the other by 10 cm find the length of each of its sides ​

Answer 1

Answer: L = 30 , B= 30

Step-by-step explanation:

Perimeter of parallelogram = 2(L+B)

L=B+10 (given)

P = 2(B+10+B)

4B = 120

B = 30cm

L = B+10 = 40cm

Answer 2

$\large\underline\pink{Given:-}$

• The perimeter of a parallelogram is 140cm.
• One of the sides of longer then the other by 10cm

$\large\underline\pink{To find:-}$

• Fine the length of each sides ....?

$\large\underline\pink{Solutions:-}$

• Let the 1st sides of parallelogram be a = x cm
• Let the 2nd sides of parallelogram be b = x + 10 cm

perimeter of parallelogram = 2(l + b)

140 = 2(x + x + 10)

140 = 2x + 2x + 20

140 = 4x + 20

4x = 140 - 20

4x = 120

x = 120/4

x = 30

1st side = x

⟹ 30cm

2nd side = x + 10

⟹ 30 + 10

⟹ 40 cm

$\large\underline\pink{More \: \: Information:-}$

• Area of parallelogram = base × height
• perimeter = 2 (l + b)

where,

• l = length
• b = breadth
• a = area
• p = perimeter
