Question

Write the area (in square cm) of the shapes below:

Answer 1

• Area of triangle A = Half of area of a rectangle
  = `1/2 xx 12`
  = 6 square cm.
• Area of square B = 4 complete squares + 8 half squares + 4 quarter squares
  = `4 + 1/2 xx 8 + 1/4 xx 4`
  = 4 + 4 + 1
  = 9 square cm
• Area of shape C = `2 + 1/2 xx 0 + 2`
  = 2 + 2
  = 4 square cm
• Area of shape D = `5 + 1/2 xx 2 + 0`
  = 5 + 1
  = 6 square cm
• Area of shape E = `18 + 1/2 xx 6 + 0`
  = 18 + 3
  = 21 square cm
• Area of shape F = `4 + 1/2 xx 0 + 4`
  = 4 + 4
  = 8 square cm.
