To find the area of the deck, we need to calculate the area of triangle and rectangles
Lets find the area of triangle A
Area of triangle = [tex] \frac{1}{2} * base * height [/tex]
base = 9 and height =10
So area of triangle A = [tex] \frac{1}{2} * 9 * 10 [/tex]= 45
Area of rectangle = Base * height
Base of rectangle B = 9ft
Height of rectangle B = 12ft
Area of rectangle B = 9*12 = 108 square feet
Base of rectangle C = 24ft
Height of rectangle C = 22ft
Area of rectangle C = 24 * 22 =528 square feet
Area of the deck = Area of A + area of B + area of C
= 45 + 108 + 528
= 681 square feet
