The area of the triangle, trapezoid, rectangle and total area are 7. 5 ft², 10. 5 ft², 0.8 ft² and 18. 8 ft² respectively.
1. Area of a triangle = 1/2 base × height
Area = 1/2 × 5 × 3
Area = 1/2 × 15
Area = 7. 5 ft²
2. Area of trapezoid = [tex]\frac{a + b}{2} h[/tex]
a = 4ft
b = 0. 2ft
h = 5ft
Area = [tex]\frac{4 + 0.2}{2}* 5[/tex]
Area = [tex]\frac{4.2}{2} * 5[/tex]
Area = 2.1 × 5
Area = 10. 5 ft²
3. Area of rectangle = length × width
Area of rectangle = 0. 2 × 4
Area of rectangle = 0. 8 ft²
4. Total area of tree = area of triangle + area of trapezoid + area of rectangle
Total area of tree = 7. 5 + 10. 5 + 0. 8
Total area of tree = 18. 8 ft²
Thus, the area of the triangle, trapezoid, rectangle and total area are 7. 5 ft², 10. 5 ft², 0.8 ft² and 18. 8 ft² respectively.
