Kumiko is designing a rock garden in the shape of a trapezoid. She decides that the garden should have a front width of 8 m and a depth of 5 m. The area must be 50 m2
to fit her design.
b = ?
A = 50 m2
h = 5 m
a = 8 m
How wide, to the nearest number of whole metres, should Kumiko's garden be at the
back?
