Printable Playground With a Corner Sandpit Area Worksheet gives learners a diagram, one worked example and five questions. The student sheet leaves space to show work. A second printable page gives the steps for each answer.
Start with the model
Find the area of the whole rectangle. Subtract the missing corner, or add two rectangles that cover the shaded part.
Outer width 12 m, outer height 8 m, upper-right cutout width 2 m and depth 4 m.
Worked example
The outer rectangle measures 12 m by 8 m. Its area is 12 × 8 = 96 m².
Ask the learner to point to the information used in the example. When they move on to the exercises, have them record the quantity, unit or label that each step represents.
Practice questions
- Find the missing corner area.
- Find the shaded paved area.
- Find the length of the short top edge.
- Find the shaded area by adding the left rectangle and the bottom-right rectangle.
- If the corner became 1 m deeper at the same width, how much shaded area would disappear?
Separate answer key
- 2 × 4 = 8 m².
- 96 − 8 = 88 m².
- 12 − 2 = 10 m.
- 10 × 8 + 2 × 4 = 80 + 8 = 88 m².
- The extra strip is 2 m by 1 m, so 2 m² would disappear.
