Area is the measure of the surface of a 2-dimensional figure. Area is measured in square units, as shown in the title.
Each type of figure has a specific formula to solve for the area of a figure:
Each type of figure has a specific formula to solve for the area of a figure:

The formula for the area of a rectangle is: A = b x h or A = l x w
To solve:
1. Plug in the numbers A = 6in x 14in
2. Multiply A = 84 square inches
To solve:
1. Plug in the numbers A = 6in x 14in
2. Multiply A = 84 square inches

The formula for the area of a triangle is: A = 1/2 (base x height) or (base x height) / 2
To solve:
1. Plug in the numbers A = 1/2 (10 x 8)
2. Multiply A = 1/2 (80) --> A = 40 square units
To solve:
1. Plug in the numbers A = 1/2 (10 x 8)
2. Multiply A = 1/2 (80) --> A = 40 square units

The formula for the area of a trapezoid is: A = 1/2 (base 1 + base 2) x height
To solve:
1. Plug in the numbers A = 1/2 (5 + 7) x 6
2. Multiply A = 1/2 (12) x 6 --> A = 6 x 6 --> A = 36 square units
To solve:
1. Plug in the numbers A = 1/2 (5 + 7) x 6
2. Multiply A = 1/2 (12) x 6 --> A = 6 x 6 --> A = 36 square units
