Find the area of a rectangle if three of its corners are (-3.7, -3.1), (1.2, -3.1), and (1.2, 5.3). Hint: find the 4th corner first.

I made a rough sketch, and I bet the missing point is
(-3.7 , 5.3)

length = 1.2 - (-3.7) = 4.9
width = ...

area = length x width
= ...

How do you solve for the length you don't have to slove it but what would the formula be ?...

hard to believe your class materials don't include the formula for finding the distance between two points. Think Pythagorean Theorem.
