Question

10. By splitting the following figures into rectangles, find their areas (The measures are given in centimetres). 5 (a) 3 1 (b) 2. 3 3 2 4 4 3 3​

Answer 1

Step-by-step explanation:

"(a) Area of HKLM = 3 x 3 = 9 cm.sq

Area of IJGH = 1 x 2 = 2 cm.sq

Area of FEDG = 3 x 3 = 9 cm.sq

Area of ABCD = 2 x 4 = 8 cm.sq

Total area of the figure = 9 + 2 + 9 + 8 = 28 cm.sq

(b) Area of ABCD = 3 x 1 = 3 cm.sq

Area of BDEF = 3 x 1 = 3 cm.sq

Area of FGHI = 3 x 1 = 3 cm.sq

Total area of the figure = 3 + 3 + 3 = 9 cm.sq"

Answer 2

) Area of figure (a)

=Area of[(1)+(2)+(3)+(4)]

=(4×2)+(6×1)+(2×3)+(2×4)

=8+6+6+8

=28 square cm

ii) Area of figure (b)

=Area of[(1)+(2)+(3)]

=(5×1)+(2×1)+(2×1)

=5+2+2

=9cm
