Use a ruler to make any measurements you need to find the area of each shape. Refer to your formulas to find out which measurements you will need. Record your measurements in a table.
Calculate the area of each shape you used. Find the area of at least one shape by composing a rectangle. Find the area of at least one shape by decomposing it into simpler shapes. Record your calculations in a table.
shape Example: Square
area of formula: A=s ^2
meaurements: s = 2 in.
area:A = 4 sq. in.
| Shape | Measurements | Area Calculation |
|---------------|-----------------|------------------|
| Rectangle | Length = 5 in. | A = 5 * 4 = 20 sq. in. |
| | Width = 4 in. | |
| | | |
| Triangle | Base = 6 in. | A = 0.5 * 6 * 3 = 9 sq. in. |
| | Height = 3 in. | |
| | | |
| Circle | Radius = 2 in. | A = π * 2^2 ≈ 12.57 sq. in. |
