Answer:
A'' = (1, -2)
Step-by-step explanation:
First we apply the translation:
(4-5, 3-1) = (-1, 2)
Next we apply the rotation. The rule for a 180 degree rotation is that every point (x, y) is mapped to (-x, -y):
(-1, 2) → (1, -2)
Answer:
The length of the base is 
Step-by-step explanation:
Since we know the formula to find the area of a triangle is
, we can plug in and solve for b. When we plug into the formula we get:
= 
First multiply by 2 on both sides to get rid of the 1/2 on the left. After doing this we get:

Then we can multiply by 5 on both sides to get rid of the 1/5 on the left. After doing this we get out answer:

Here is the answer in exact form or decimal form.
137 1/4 sq ft or the measurement
