(8) The length of a rectangle is 5 cm. more than its breadth. If
the perimeter of the rectangle is 90cm, find its length and
breadth.
Please answer it as fast as possible

Answer 1

Answer:

b = 20cm and l = 25cm

Step-by-step explanation:

Let the breadth be = x

Then length will be = x + 5

Perimeter of the rectangle = 2( length + breadth)

90 = 2( x + x + 5)

90 = 2(2x + 5)

90/2 = 2x + 5

45 = 2x + 5

45-5 = 2x

40 = 2x

x = 40/2

x = 20cm

Thus, breath is 20 cm and length is 25 cm
