I NEED HELP WITH GEOMETRY

a. 136

b. 92

Step-by-step explanation:

a. Find the area of the triangle and the area of the rectangle, then subtract the area of the rectangle by the triangle.

Area of triangle: bxh / 2 = 32x16 / 2

                                       = 512 / 2

                                       = 256

Area of rectangle: bxh = 20 x 6

                                     = 120

Total area: 256 - 120 = 136

b. Just like a., find the area of the white triangle and the rectangle, then subtract the area of the triangle by the rectangle.

Area of triangle: bxh / 2 = 23x8 / 2

                                       = 184 / 2

                                       = 92

Area of rectangle: bxh = 23 x 8

                                     = 184

Total area: 184 - 92 = 92

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
