Question

What is the area of the rectangle?

50 units squared by 2

54 units squared by 2

60 units squared by 2

65 units squared by 2

Answer 1

The answer is: 60 units².

The explanation is shown below:

1. The area of the rectangle can be calculated with the following formula:

`A=L*W`

Where L is the length and W is the width.

2. You can calculate the length and the width by using the formula for calculate the distance between two points:

`d=\sqrt{(x_2-x_1))^(2)+(y_2-y_1))^(2)}`

3. The length is:

`L=\sqrt{(8-(-1))^(2)+(-2-1)^(2)}=9.48units`

4. The width is:

`W=\sqrt{(-3-(-1))^(2)+(-5-1)^(2)}=6.32units`

5. Therefore, the area is:

`A=(9.48units)(6.32units)=59.9units^(2)=60units^(2)`
