Question

the width of shriya's garden is 2/3 of its length . if it's perimeter is 40 cm find it's dimension ​

Answer 1

Step-by-step explanation:

Width of garden (Breadth) = 2/3 x

Perimeter of the garden = 40 cm

Let length of the garden be x

Perimeter = 2(x + 2/3 x) = 40

= 2(3x + 2x / 3) = 40

=2( 5x/3) = 40

= 10x/3 = 40

= 10 x = 40 x 3

10 x =120

x = 120/10

x =12 cm

Length of garden = 12 cm

Breadth of garden = 2/3 x 12 = 24/3 = 8 cm

Dimensions :-

Length = 12 cm

Breadth = 8 cm

Verification

2(l + b) =40

2(12 + 8) = 40

2 (20) = 40

40 = 40
