Answer:
1. Area of rectangle = lw
= 16 X 12
= 192 cm²
Area of triangle = bh÷2 or ½bh
=½(12×14)
= ½(188)
=94cm²
Shaded region: 192 cm² - 94cm² = 98cm²
2. Area of square= S×S
=6×6
=36m²
Area of a circle: πr² ( if u add the two semi it becomes a circle)
=3.14(3)²
=3.14(9)
=28.26m²
Shaded region: 36-28.26 =7.74m²
(If the u want the semi circle have a solution each,just use the formula ½πr²)
