Answer:
A.
Step-by-step explanation:
The figure is made up of a rectangle and two triangles.
The dimensions of the 3 polygons are:
Rectangle: 8 m by 15 m
Triangle 1: 15 m base and 7 m height
Triangle 2: 9 m base and 8 m height
Total area =
= [8(15) + 15(7)/2 + 9(8)/2] m^2
Answer: A.

Answer: Point D</h3>
See the diagram below. I drew a line through the left corner points of the red and blue quadrilaterals. This line goes through the point D. You could pick on the right corners of the original quadrilaterals and that line will also pass through point D.
Put both of those equations into slope intercept form (in order to be typed into the graphing calculator).
2x + 3y = 16.9
3y = -2x + 16.9
y = (-2/3)x + 16.9/3
5x = y + 7.4
5x - 7.4 = y
So in the graphing calculator,
Y1 = (-2/3)x + 16.9/3
Y2 = 5x - 7.4
Then find the point of intersection and the x value of that would be the solution.
You get the coordinate (2.3, 4.1). So x = 2.3, y = 4.1
Answer:
The value of y = 5⁰...........
3 feet is in 1 yard.
Therefore, 3x feet is in x yard.
