Question

The perimeter of a rectangle is 56m and the difference between it's length and breadth is 12 m.Find it's length,breadth and area.​

Answer 1

Answer:

• Length = 20m
• Breadth = 8m
• Area = 160 m²

Step-by-step explanation:

Let,

Breadth = x

Length = x + 12

We know that,

Perimeter = 2 (l + b)

Hence,

2(x + x + 12) = 56

⇒2x + 2x + 24 = 56

⇒4x + 24 = 56

⇒4x = 56 - 24

⇒4x = 32

⇒x = 8

Therefore ,

• Breadth = 8m
• Length = 8m + 12m = 20m
• Area = 8m × 20m = 160m²

Hope it helps you.
