**step-by-step solution**
6. We have two shapes, named rectangle and square.
FORMULA :
or side * side = area of square
or length * width = area of rectangle
step 1 : get the area of the square
or 4 * 4 = 16cm
step 2 : get the area of the rectangle
12 * 8 = 96cm
step 3 : subtract the area of the square from the area of rectangle
96 - 16 = 80cm
FINAL ANSWER FOR #6 = 80CM
7. We have two shapes, named rectangle and triangle.
or base * height ÷ 2 = area of triangle
step 1 : get the area of triangle
base = 14, height = 10
14 * 10 = 140cm
140 ÷ 2 = 70cm
step 2 : get the area of rectangle
length = 16, width = 10
16 * 10 = 160cm
step 3 : subtract the area of triangle from the area of rectangle
160 - 70 = 90cm
FINAL ANSWER FOR #7 = 90cm
8. We have two circles with two different circumference.
GIVEN :
Big Circle = 21cm radius, Small Circle = 7cm radius
or pi(3.14) * radius squared
step 1 : get the area of the smaller circle
3.14 * = 153.86cm
step 2 : get the area of the bigger circle
3.14 * = 1,384.74cm
step 3 : subtract the area of the small circle from the area of big circle
1384.74 - 153.86 = 1230.88cm
FINAL ANSWER FOR #8 = 1230.88cm
9. We have two shapes, named rectangle and triangle.
step 1 : get the area of the rectangle
3 * 4 =12m
step 2 : get the area of the triangle
6 * 7 = 42
42 ÷ 2 = 21cm
step 3 : subtract the area of rectangle from the area of triangle
21 - 12 = 9m
FINAL ANSWER FOR #9 = 9m
10. We have two shapes, named square and circle.
Since radius is the half of the circle, we can assume the half of square is 5cm and so the half of circle is also 5cm.
radius = 5cm
or pi(3.14) * radius squared = area of circle
step 1 : get the area of circle
3.14 * = 78.5
step 2 : get the area of square
or 10 * 10 = 100
step 3 : subtract the area of circle from the area of square
100 - 78.5 = 21.5cm
FINAL ANSWER FOR #10 = 21.5cm

10. We have two shapes, named square and circle.
Since radius is the half of the circle, we can assume the half of square is 5cm and so the half of circle is also 5cm.
GIVEN :
radius = 5cm
FORMULA :
step 1 : get the area of circle
3.14 *
= 78.5
step 2 : get the area of square
step 3 : subtract the area of circle from the area of square
100 - 78.5 = 21.5cm
FINAL ANSWER FOR #10 = 21.5cm
