the floor of a shed has an area of 70 square feet. the floor is in the shape of a rectangle whose length is 4 feet less than twice the width. find the length and the width of the floor of the shed.

  length: 10 ft; width: 7 ft.

Step-by-step explanation:

Factorizations of 70 are ...

  70 = 1·70 = 2·35 = 5·14 = 7·10

The last pair of numbers has the relation that 2·7 -10 = 4, so the numbers 7 and 10 can be used for width and length.

The length is 10 ft; the width is 7 ft.
