This diagram is the premises of the house. The length for the premises is 10.5m and width is 8.5m. The length for the garage is 2.5m. Calculate the area for the house.

[Formula]

(10.5)(8)-(6)(3)-(2.5)(2.5)=84-18-6.25=59.75

59.75m2

For this kind of question, we can solve in several ways.

First one is subtracting the extra area from rectangle and the second one is dividing the area to two and add the area at last.
