Answer 1

Answer:

12m

Step-by-step explanation:

let breadth = b

length = 4 × b = 4b

total area = b × 4b = 4b^2

area of playground = 12

1/3 * 4b^2 = 12 => b^2 = 9

b = 3

length = 4b = 4 × 3 = 12 m

Answer 2

Answer:root 3

Step-by-step explanation:

B=x L=4x A=12, so

A=l.b

12=4x×x

x= root 3
