Question

The area of a children square playground is 50m squared.

a. what is the exact length of the playground
2. pine logs 3m long are to be laid around the playground. How many logs will need to be bought?

Answer 1

a. solution

Area = 50 m^2

Area of square = l^2

or, 50 m^2 = l^2

or, √50m^2 = l

or, 5√2 m= l

Hence, The exact length of the playground is 5√2 m.
