What is the area of the rectangle below?
1.-1 , -3,1 , 3,4 7,2
2√5
3√5
10√5
30
The area of a rectangle is calculated by multiplying its length by its width.
The length of the rectangle can be calculated using the coordinates (-1, -3) and (1, 3):
length = absolute value of (3 - (-3)) = 6
The width of the rectangle can be calculated using the coordinates (1, 3) and (7, 2):
width = absolute value of (7 - 1) = 6
Therefore, the area of the rectangle is:
Area = length × width = 6 × 6 = 36
So the correct answer is 36.
