The breadth of a rectangle is 5 more than one third of the length.
. The perimeter of the rectangle is 42 cm.
Find the length of the rectangle.​

Answer 1

Answer:

let the length x

breadth 1/3x+5

2(x+1/3x+5) is equal to 42

Answer 2

Answer:

12

Step-by-step explanation:

let the length be x

then breath = 5+1/3x

perimeter = 2(l+b)

42 = 2(x+5+x/3)

21 = 3x+15+x/3

63 = 4x+15

48 = 4x

x = 12
