Sense Jane wants to find the area of the trapezoid. To find
the area of a trapezoid, add the two bases,
multiply by the height, then divide by 2. The
bases and height of the trapezoid are shown.
Represent the area of the trapezoid with a
numerical expression.

Step-by-step explanation:

First we find the average of 3m and 7m:  It is 10 m/2, or 5 m.

Multiplying this result by the height (3 m) results in 15 m^2.

This is the area of this particular trapezoid.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

a)(x-2)^2+(y-1)^2=9
