Answer 2

1)

area of shaded portion = (4×4) ×2 cm²

=32 cm²

2) area of shaded portion

= {(20×2) + (12×3)} - (2×3) cm²

= (40 + 36) - 6

= 76 - 6

=70 cm²

3) area of 1 shaded box = 3×3 cm²

=9cm²

" " 4 " " = 9 × 4 cm²

=36 cm²

4) area of the shaded Trapezium

=1/2 (25 + 5) × 15 cm²

= 1/2 × 30 × 15 cm²

= 225 cm²
