Question

The length of a rectangle is twice the breadth. Its perimeter is 90cm,then its length and breadth are...........​

Answer 1

Answer:

Length = 30 cm

Breadth = 15 cm

Step-by-step explanation:

Given : perimeter of rectangle = 90 cm

Let the breadth = x cm

Then,

length = 2x cm

Therefore,

perimeter of rectangle = 2( langth + breadth)

90 = 2 (2x + x)

2(3x) = 90

6x = 90

x = 90/6

x = 15

Therefore,

Breadth = x cm = 15 cm

Length = 2x cm = 2×15 cm = 30 cm

I hope this will help you!
