Question

12. Find the area of the shaded region for each of the following.
​

Answer 1

Answer:

205,

Step-by-step explanation:

Figure 1

Area of shaded region = area of trapezium - area

of triangle

=1/2(sum of || side) x height - 1/2 base x height

=1/2(16+22) x 10 + 1/2x10x3

38 x 5 + 5 x 3

= 190 + 15

=205

Figure

Area = ar(trapezium) + area of triangle

=1/2(18+24)x10 + 1/2 x 5 x 24

= 42x5 + 5 x 12

=210 + 60

=270
