Determine the perimeter of the rectangle if its area is 64 m2 and its length is 16 m.
A: 40 m
B: 45 m
C: 30 m
D: 38 m
In order to determine the perimeter of the rectangle, we first need to determine the width (w). The area of a rectangle is calculated by multiplying length×width
, so we can use the following equation to solve for our missing value (w).
Area = l × w
64 m2=16 × w
Divide both sides by 16 to solve for w.
w = 4, or 4 m
Now that we know the length and the width, we can use the formula Perimeter=(length+width)×2
in order to solve for the perimeter. When we plug in 16 m for our length and 4 m for our width, we have the following: Perimeter=(16m+4m)×2
which simplifies to 40 m. The perimeter of the rectangle is 40 meters.
