Determining the Area of Rectangles Using Multiplication
T.I.P.S.
Students must be able to find the area of rectangles in problems based on the number of rows and number of square units in a row, using multiplication.
Example
Remy’s family wants to turn their outdoor patio into an indoor sunroom. Part of the plan calls for covering the concrete slab with carpet squares that are 1 foot long on each side.
Based on the illustration below, how many carpet squares are needed to cover the slab? Explain how you determined the number of squares they needed.
