Answer:
The perimeter of the rectangle is 54 meters.
Step-by-step explanation:
In order to find the perimeter of the rectangle, which is the sum of all the sides, we need to know not only the length, but also the width. The formula for area of a rectangle is A = length x width. Setting up an equation to find width 'w', we get: 162 = 18 x w. Using inverse operations, we divide both sides of the equation by 18 to get w = 9. Since we now know that w = 9 and l = 18, we can find the perimeter using the following equation: P = 2w + 2l or P= 2(9) + 2(18) or P=54 meters.
