AREA OF GEOMETRIC SHAPES - SIMPLE

Concept: Area is a measure of the surface of a flat figure. Area is measured in square units. Area tells how many square units it takes to cover the space inside the figure. Listed below are the formulas for finding the area of geometric shapes.

Chart of Formulas for Finding the Area of Geometric Shapes
Square | A = s2 |
Rectangle | A = lw |
Triangle | A = bh |
Circle | A = r2 |
Parallelogram | A = bh |
Trapezoid | A = (b1 + b2)h |

Steps for Finding the Area of Geometric Shapes

Step 1 | Choose the proper formula for the figure in the problem.
Step 2 | Substitute the values.
Step 3 | Solve.
Step 4 | Write the final answer.

Example Solve for area, given b=14 and h=3

Step 1 | Choose the proper formula for the figure in the problem. | A = bh
Step 2 | Substitute the values. | A = 14 x 3
Step 3 | Solve. | A = 14 x 3 A = 42
Step 4 | Write the final answer. | A = 42
