Answer 1

Answer:

136

Step-by-step explanation:

Step 1 ) Area of shaded portion = area of rectangle - (area of left triangle + area of right triangle)

Step 2)  Area of rectangle = 20 - 10 = 200

Step 3) Area of left triangle = $1/2 * base * height$

                                               = 1/2 * 4 * 12 = 24

Step 4) Area of right triangle = $1/2 * base * height$

                                               = 1/2 * 8 *10 = 40

Step 5) Area of shaded portion = 200 - (40 + 24)

                                                     = 200 - 64

                                                      = 136
