Answer:
51 ft²
Step-by-step explanation:
The figure is composed of two different triangles (triangle 1 and 2) and a rectangle
Area of the composite figure = area of triangle 1 + area of triangle 2 + area of rectangle
✔️Area of triangle 1 = ½*bh
b = 3 ft
h = 2 ft
Area of triangle 1 = ½*3*2 = 3 ft²
✔️Area of triangle 2 = ½bh
b = 3 ft
h = 3 ft
Area of triangle 2 = ½*3*3 = 4.5 ft²
✔️Area of rectangle = L*W
L = 3 + 8 = 11 ft
W = 4 ft
Area of rectangle = 11*4 = 44 ft²
✅Area of the composite figure = 3 + 4 + 44
= 51 ft²
