Question

The length of a rectangle is 3 centimetre more than its breadth.if the perimeter is 22 cm find the length and

breadth of the rectangle​

Answer 1

Let the Breadth of the rectangle be x cm. => x = 4cm. And Length = 3 + 4 = 7cm.

Answer 2

Answer:

22 = 2 ( length + breadth )

let breadth = x

length = x+3

22 = 2 ( x + x + 3)

22 = 2 (2x+3)

22 = 4x + 6

22-6 = 4x

16 = 4x

x = 4

so

breadth = 4

length = x+3 = 4+3 = 7
