Question

. The length of a rectangle is twice its breadth. If the perimeter is 72 metre, find the length and breadth of the rectangle.

Answer 1

Answer:

l = 24m

b = 12m

Step-by-step explanation:

Given l = 2b  , (taking l and b be the length and breadth of the rectangle)

also, perimeter, p = 2(l+b) = 72m

=> 2l+2b = 72m

=> 2l + l = 72m

=> 3l = 72m

=> l = 72/3 m

=> l = 24m

=> 24 = 2b

=> b = 24/2m

=> b = 12m

so, length of the rectangle, l = 24m

and breadth of the rectangle b = 12m

Answer 2

Step-by-step explanation:

Lenght=2x

Breadth=x

=2(l+b)

72=2(2x + x)

72=4x + 2x

72=6x

72/6=x

12=x

Now,

Breadth=x=12m

Length=2x=2(12)

=24m
