Answer:

what is asked: what is the perimeter of the plot of land?

what are given: length = 3(width), width = 4m

Write the equation: Perimeter = 2 (3x4 + 4)

Solve: Perimeter =  2 (3x4 + 4)

                    =  2 (12 + 4)

                    =  2 (16)

                    =  32m

Check your answer: The perimeter of a rectangle is the total length of all the sides of the rectangle which can be found by using the formula a+b+a+b.

if a = 12 and b = 4 then 12+4+12+4 = 32
