 226.5 ft²

Step-by-step explanation:

I divided the image into 3 rectangles and 1 triangle.

top rectangle: length = 9, height = 4          -->      A = 9 x 4 =   36

middle rectangle: length = 15, height = 7   -->      A = 15 x 7 = 105

bottom rectangle: length = 18, height = 4  -->      A = 18 x 4 =   72

triangle: base = 9, height = 3                      -->  A = (9 x 3)/2 =   13.5

Total                                                                                       =  226.5

Step-by-step explanation:

Area = area of rectangle 1 +area of rectangle 2 +area of rectangle 3 + area of triangle

= 9* 15 + 6*11 + 3*4 + (1/2)*3*9

= 135 + 66 + 12 + 13.5

= 226.5 sq.ft

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
