Question

06. The length of a rectangle is twice its breadth. If the perimeter is 72 metre, find the length a
breadth of the rectangle.
2:
22​

Answer 1

Step-by-step explanation:

Given, the length of rectangle is twice it's breadth

length = L, Breadth = B

L = 2B

Perimeter = 2 (l + b)

72 = 2 (2B + B)

36 = 3B

B = 12 ---------(1)

:: l = 2b

= 2 ( 12 )

Length = 24

Answer 2

Step-by-step explanation:

The breadth of a rectangle :- x

The length of a rectangle :- 2x

The perimetre of the rectangle :- 72m

☞︎︎︎2(l+b)=72

☞︎︎︎2(2x+x)=72

☞︎︎︎2(3x)=72

☞︎︎︎6x=72

☞︎︎︎x=72/6

☞︎︎︎12

breadth :- (x) = 12

length :- 2(x) = 2(12) = 24

CHECK :-

☞︎︎︎2(l+b)=72

☞︎︎︎2(12+24)=72

☞︎︎︎2(36)=72

☞︎︎︎72=72 (VERIFIED✓)
