The area of the whole figure = area of triangle A + area of triangle B = 7.5 + 15 = 22.5 square units
How to Calculate the Area of a Triangle?
If h is the height of a triangle, and b is the length of its base, the area of the triangle is calculated as:
Area = 1/2 × b × h.
Find the area of triangle A:
Height of triangle A (h) = 3 units
Length of base of triangle A (b) = 5 units
Plug in the values into 1/2 × b × h to find the area o triangle A:
Area of triangle A = 1/2 × 5 × 3
Area of triangle A = 15/2
Area of triangle A = 7.5 square units.
Find the area of triangle B:
Height of triangle B (h) = 3 units
Length of base of triangle B (b) = 10 units
Plug in the values into 1/2 × b × h to find the area o triangle A:
Area of triangle A = 1/2 × 10 × 3
Area of triangle A = 30/2
Area of triangle A = 15 square units.
The area of the whole figure = area of triangle A + area of triangle B = 7.5 + 15
The area of the whole figure = 22.5 square units
