What is the area of a rectangle with vertices at (2, 3), (7, 3), (7, 10), and (2, 10)?

A44 units2
B30 units2
C24 units2
D35 units2

Verified Answer :

Given:
x     y
2     3
7     3
7   10
2   10

It is easier to graph these vertices to avoid confusion. 

Length: basis is the y-values : 10 - 3 = 7 units
Width: basis is the x-values: 7-2 = 5 units

Area = Length Width
A = 7 units
5 units
A = 35 units²    Choice D.
