The breadth of a recrangle 1/3rd is in of its length, is the perimeter is
40 metres, find its area​

Answer 1

Answer:

75m²

Step-by-step explanation:

let length be x

breadth =1/3 x

perimeter = 2 (l+b)

40 = 2(l+b)

40/2= x + x/3

20 = (3x + x )/ 3

20×3 = 4x

60 =4x

x= 15 m

length =15 m

breadth = 15/3 =5 m

Area = l×b

= 15×5

=75 m²
