What is the area of this trapezoid? a. 14 m2 b. 18 m2 c. 21 m2 d. 35 m2

B

Step-by-step explanation:

If we draw another vertical line on the other side, we can split this into a rectangle and two triangles.  The width of the rectangle is 5 m, so the base of the triangle on the left is 1 m, just like the triangle on the right.

The area is therefore the sum of the areas of each shape:

A = Arectangle + 2Atriangle

A = (5 m)(3 m) + 2(½ (1 m)(3 m))

A = 18 m²

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

faster, im not sure why but i know it is faster
