Question

The area of a rectangle is 14 square units. it has the side length of x and y. given each value for x, find y.

1. x = 4 and 1/5
2. x = 2 and 1/3
3. x = 7/6​

Answer 1

1. y = 3 1/3

2. y = 6

3. y = 12

Explanation:

A = xy => xy = 14 => y = 14/x

1. x = 4 1/5 = 21/5

y = 14/x = 14/(21/5) = (5 x 14)/21 = 10/3 = 3 1/3

2. x = 2 1/3 = 7/3

y = 14/x = 14/(7/3) = (3 x 14)/7 = 6

3. x = 7/6

y = 14/x = 14/(7/6) = (6 x 14)/7 = 12
