Question

What are the dimensions of a 60 – square meter rectangle that can be enclosed by 32 m of fencing material?

Answer 1

Answer:

Explanation :

Let the length be x and breadth be y

Given, area = 60 ( xy)

Perimeter = 32 { 2 (x + y)}

We have,

xy = 60 32 = 2 (x+y)

or x = 60/y ...1 16 = x+y ...2

Substituting value of x in ...2

16 = 60/y +y

By solving, we get y = 6 and x = 10

Hence the dimensions are 6m and 10m ans
