Answer:
it should be 70
Step-by-step explanation:
The y value should be -128
<u>A
</u><u />You can find the area of a trapezoid with a+b/2*h. If you do so with those numbers, you will get 108.
<u>B
</u><u /><u />If you multiply 2.5 by 108, you can find the cost to tile the entire trapezoid. This is $270 even.
<u>C
</u><u />To solve for the area of a parallelogram, you can simply multiply bh. If you do so with these numbers, you will get 96.
<u>D
</u><u />If you multiply 3 by 96, you can find the cost to tile the entire parallelogram. This is $288 even.<u>

now this assuming that M partitions XY on a 4:1 ratio "from X to Y", Check the picture below.
