Draw a line from the top of the 3 m line to the 10 m line so that the new line meets the the 10 meter line at right angles. The part you are interested in should be 4 meters long.

Top rectangle.

Area = L * W

L = 7 (10 - 3 = 7)

W = 4

Area = 4* 7 = 28

Bottom rectangle

Area = L * W

L = 12

W = 3

Area = 12 * 3 36

Total Area 64
