Answer:
Step-by-step explanation: Go from one point to the other without crossing. From the bottom point to the top, you are rising 5. then going right 3. up and right is posotive and down and left is negative. so the rise over run is 5/3. then divide. 1.66...7, Sorry if this did not help:(
Your answers are correct. Q3 Is > and Q4 is <
So the formula for the area of a trapezium is
area = (a + b)/2 * h
*a is the short side
* b is the long side
*h is the height
so let's plug in the values we already know: area, long base, short base. Here's how the formula looks now...
6550 = (150 + 85)/2 * h
*so, we need to find 'h'
use algebra to find it.
6550 = (235/2) * h
6550 = 117.5 * h
6550/117.5 = h
h = 55.74 (approx)
