Full solution

Q. Richard makes a number 77 by cutting out a rectangle and a parallelogram.\newlineFind the area of the number 77 .\newlineArea = = \square cm2 \mathrm{cm}^{2}
  1. Identify dimensions: Identify the dimensions of the rectangle and parallelogram. Assume the rectangle has a base of 1cm1\,\text{cm} and a height of 5cm5\,\text{cm}. Assume the parallelogram has a base of 1cm1\,\text{cm} and a height of 2cm2\,\text{cm}.
  2. Calculate rectangle area: Calculate the area of the rectangle using the formula Area=base×height\text{Area} = \text{base} \times \text{height}. For the rectangle, Area=1cm×5cm=5cm2\text{Area} = 1 \, \text{cm} \times 5 \, \text{cm} = 5 \, \text{cm}^2.
  3. Calculate parallelogram area: Calculate the area of the parallelogram using the formula Area=base×height\text{Area} = \text{base} \times \text{height}. For the parallelogram, Area=1cm×2cm=2cm2\text{Area} = 1 \, \text{cm} \times 2 \, \text{cm} = 2 \, \text{cm}^2.
  4. Find total area: Add the areas of the rectangle and parallelogram to find the total area of the number 77. Total Area = 5cm2+2cm2=7cm25 \, \text{cm}^2 + 2 \, \text{cm}^2 = 7 \, \text{cm}^2.
