In order to find the area of a rectangle, the formula is L*W (Length multiplied by Width). Our goal is to find these two measurements, so we will take the following steps:
1) Plot the coordinates on a graph (I have attached a visual guide)
2) Using the Pythagorean Theorem, or the Distance formula we can find the length and width:

3) We will use these values in the Area formula for a rectangle (L*W)
4) After solving the Area formula with the values retrieved from the Distance Formula we find that
the area is roughly 30 units squared.
Answer:
2x +21
Step-by-step explanation:

X= 5 or -8
Add all the like terms and set it equal to 49, use quadratic formula or factoring.
Answer:
it is this one
Step-by-step explanation:
because since x is 4 and y is 8 that one matches up better than any other one
Answer:
slope is 4
