Question

the perimeter of a parralogram is 92cm. if one side is greater than its adjacent side by 10 cm .find its sides

Answer 1

Let the length be b + 10 and breadth be b
Perimeter = 2(l+b)
2(b+b+10) = 92 
2b + 10 = 46
2b = 36
b = 18
Therefore, l = b + 10 = 18 + 10 = 28.

~ Peace.

Answer 2

Step-by-step explanation:

Let one side of the parallelogram be x cm The length of the other side be x + 10 cm

The perimeter of parallelogram = 92 cm

⇒ x + x +10 + x + x + 10 = 92

→ 4x + 20 = 92

→ 4x = 72

⇒ x = 18

The length of the side of parallelogram is 18 cm Its adjacent side is 28 cm
