Question

The length of a rectangle is 1 cm more than its breadth. If the perimeter is 30 cm, find the length and breadth.

Answer 1

Answer:

length = 8cm

breadth = 7cm of the given problem

Answer 2

Step-by-step explanation:

Let the breadth of rectangle be x cm

And let the length of rectangle be x+1 cm

Perimeter of rectangle = 2 ( length + breadth )

Therefore,

30 = 2 [ ( x+1 ) + x ]

30 = 2 ( x+1 + x )

30 = 2 ( 2x+1 )

30 = 4x+2

4x = 30-2

4x = 28

x = 28/4

x = 7

Therefore,

Length of the rectangle = x+1 = 7+1 = 8 cm

Breadth of the rectangle = x = 7 cm
