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.

Answer 1

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
= ...

Answer 2

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

Answer 3

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