Learning Objective
I can calculate the area of rectangles and squares using appropriate formulas.
- 1
The perimeter of a rectangle can be found by using the formula P = 2l + 2w, where l is the length and w is the width.
- 2
The area of a rectangle is found by multiplying the length by the width, and the answer is always measured in square units.
- 3
The area of a square is found by squaring the length of one of its sides, A = s², because all four sides are equal.
