Question

the perimeter of rectangle is 54 cm the breadth is less than its length by 3 cm find the length and breadth
​

Answer 1

Answer:

Length is 15 cm and bredth is 12 cm.

Step-by-step explanation:

Let the length of the rectangle be x cm.

Then the breadth of the rectangle is (x-3) cm.

Perimeter of rectangle = 54 cm

2(l+b) = 54

2 { x + (x-3)} = 54

2 ( x + x - 3 ) = 54

2 ( 2x - 3 ) = 54

4x - 6 = 54

4x = 54 + 6

4x = 60

x = 60/4

x = 15 cm

Therefore, Length = x = 15 cm

Breadth = (x-3) = 15 - 3 = 12 cm
