Question

The perimeter of a rectangle is 36 cm and the length is twice the width. What are

the dimensions of this rectangle?
Width? _____ cm
Length? ____ cm

Answer 1

Explanation:

If breadth is b,then length will be 2b,so

Perimeter=36

2(2b+b)=36

3b=18

b=6,so,l=2×6=12

So,length is 12 and breadth is 6,

Hope it helps…

Answer 2

Width __6___ cm

Length __12__ cm

Explanation:

hello :

x : the width and y : Length P : the perimeter

P=2(x+y ) but : P=36cm and : y = 2x

36 = 2(x+2x)

36 = 2(3x)

6x =36 so : x=6 cm and y = 2×6=12cm
