Question

It takes h hours to paint a rectangular wall that is x feet wide and y feet long how many minutes does it take to paint one square foot of bulletin board

Answer 1

It is given in the question that

It takes h hours to paint a rectangular wall that is x feet wide and y feet.

Area of the rectangular wall is the product of length and width that is

`Area = xy \ feet^2`

And for an area of xy square feet, it takes h hour.

So for 1 square feet, it will take

`= (h)/(xy) hours`

And for the number of minutes, we have to multiply it by 60, that is

`=(60h)/(xy) minutes`
