a rectangular vegetable garden is 4ft longer than it is wide. what are the dimensions of it covers 60 ft^2?

Find the least common multiple of 8 and 40 which is 40. The denominator will be 40. For 8 to get to 40 we have to multiply the top number by five since 8 x 5 is 40.

So we will have:

5/40

9/40 already has 40 as its denominator so we will keep the fraction like that:

5/40 + 9/40 = 14/40

14/40 can be simplified by 2.

7/20

So the answer is 7/20.

Hope this helped, have an awesome day! <3
