Answer:

264 ft²

Step-by-step explanation:

area of window = 12

area of triangle = 60

area of rectangle = 216

because they are attached together 216 + 60 = 276

276 - area of window

276 - 12 = 264

Answer:

264ft 2

Step-by-step explanation:

at square: 18•12=216ft2

at roof: [(28-18)•12]÷2=(10•12)÷2=120÷2=60ft2

minus window: 3•4=12ft2

=>216+60-12=264ft2
