Question

Peter's grandma has a trapezoidal garden, as in the picture.
a) What is the length of the fence of that garden?
b) What is the area of the garden?

The word in the top left corner in the picture is not linked to this task.

Answer 1

Length of fence = perimeter of trapezoid

                           = 12 + 6 + 5 + 5

                           = 28 meters

Area of garden = $h (\frac{base 1 + base2}{2} )$

                         = 4($\frac{12+6}{2}$)

                         = 4 x 9

                         = 36 sq. meters
