Rob builds a rectangular patio that has an area of 51 m². The patio has a width of 3 m what is the length of the patio

To find the length of the patio, we can use the formula for the area of a rectangle, which is:

Area = length * width

Given that the width is 3 m and the area is 51 m², we can substitute these values into the formula:
51 = length * 3

To isolate the length, we can divide both sides of the equation by 3:
Length = 51 / 3

Simplifying, we find:
Length = 17

Therefore, the length of the patio is 17 m.
