Question

Find the area of the rectangle whose vertices have

coordinates (-2,-2), (3,-2), (3, 4) and (-2, 4).​

Answer 1

Area = 30 square units

Explanation:

First, let's try to visualize the problem:

(-2, 4) • | • (3, 4)

|

|

___________|___________

|

(-2, -2) • | • (3, -2)

|

|

Let's find the side lengths;

(-2) - 3 = |-5|, the Base of the rectangle is 5 units.

4 - (-2) = 6, the Height of the rectangle is 6 units.

The formula for area of a rectangle is B × H.

5 × 6 = 30, so the area of the rectangle is 30 units.
