Question

The breadth of a rectangular garden is two third of its length. If its perimeter is 40 m, find its dimensions.

Answer 1

Answer:

let length be x

breadth= 2/3 X

p= 40 m

2(x+2/3X)= perimeter

x + 2/3 x = 20

3x+2x/3= 20

5x = 60

x= 12 m

length = 12

breadth = 8 m

Answer 2

Step-by-step explanation:

let las to be x and b as to be 2/3x according to question.

here, we have given perimeter of rectangle = 40 m

then, 2( l+b) = 40

2(x+2/3x) = 40

x+2/3x =40/2

x+2/3x= 20

5x/3 = 20

5x= 60

x= 12

As we know, l = x then l= 12m

and b = 2/3x so 2/3×12

b= 8m
