Question

Find the area of the polygon verticles of A(0,1)B(0,5)C(4,5) and D(6,1)

Answer 1

20

Explanation:

Draw that out on a coordinate grid, you get a trapezoid with one base 6 units long, one base 4 units long and a height of 4. Using the formula for area of a trapezoid

h(b1 + b2)/2

The height, 4, b1 is a base, 6, b2 is the other base, 4, we get

4(4+6)/2

40/2= 20
