Answer:
A. 806.5 in²
Step-by-step explanation:
The figure given is a combination of a rectangle, a trapezoid and a triangle.
The formulas for the areas of each figure:
Rectangle: length x width
Trapezoid: 
, where 
and 
are the lengths of each base and h is the height of the figure
Triangle: 1/2 bh, b = base and h = height
For each of the figures given:
rectangle: 16 x 9 = 144 in²
trapezoid: 
= 352.5 in²
triangle: 1/2(31*20) = 310 in²
310 + 144 + 352.5 = 806.5 in²
Answer:
C
Step-by-step explanation:
If it is accurate then it would have gotten the correct weight, but by going down to the thousandths it would be precise
OK: slope is rise/run so 6-1/0--1=5/1
So, 5/1 or 5 is your slope
