Answer 11

Do u know how to find the area of triangle A?

Answer 12

no

Answer 13

For a right angled triangle like triangle A, area = \(\sf 0.5 \times base \times height\)

Answer 24

Sorry!
I had to leave yesterday.

So, to calculate the area of shaded region we divided that region into triangle A, rectangle B and C. Now to calculate the are we will calculate the areas of all the 3 regions one by one and finally sum up them together.

Area of Triangle A:

Area of a right angled triangle is given by 0.5 * base * height.

Here, base of the triangle =8+2=10 (see the figure) and height = 8-2-2=4.

\(\therefore\) Area = 0.5 * 4 * 10 =?

Answer 25

Now area of rectangle = Length * Breadth.

Length of Rectangle B and C are 10 and 8 respectively and breadth for rectangle B and C are 1 and 2 respectively. Calculate the area of each of them and finally add area of triangle A, area of rectangle B and C. That would be the area of shaded region.
