    ok,, to find the area of shade region we will have to divide the region into smaller parts.

    Now we can find the whole area by finding the area of triangle A, rectangle B and rectangle C and adding them all

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

    What is the area, in square feet, of the shaded region?

    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 =?

    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.
