Question

By splitting the following figures into rectangles, find their areas (The measures are given in centimetres).

Answer 1

(a) Area of HKLM = 3 x 3 = 9 cm² 
Area of IJGH = 1 x 2 = 2 cm² 
Area of FEDG = 3 x 3 = 9 cm² 
Area of ABCD = 2 x 4 = 8 cm² 
Total area of the figure = 9 + 2 + 9 + 8 = 28 cm²

---

(b) Area of ABCD = 3 x 1 = 3 cm² 
Area of BDEF = 3 x 1 = 3 cm² 
Area of FGHI = 3 x 1 = 3 cm² 
Total area of the figure = 3 + 3 + 3 = 9 cm²
