Question

Please help me you get 24 points

I forgot how to find the area of a rectangle I know its l*w but I don't remember how to it. please help and explain step by step.

Answer 1

you only need multiple for the perimeter

Answer 2

To find length and width, you use the distance formula:

`d=\sqrt{(x_(2)-x_(1))^(2)+(y_(2)-y_(1))^(2)}`

For the length, you use the points
`(-2, 3)` and
`(1, 5)`

`d=\sqrt{(1-(-2))^(2)+(5-3)^(2)}`

`=\sqrt{3^(2)+2^(2)}`

`=√(9+4)`

`=√(13)`

For the width, you use the points
`(-2, 3)` and
`(2, -3)`

`d=\sqrt{(2-(-2))^(2)+(-3-3)^(2)}`

`=\sqrt{4^(2)+(-6)^(2)}`

`=√(16+36)`

`=√(52)`

`=2√(13)`

So we multiply:

`√(13)*2√(13)=2*13=26`
which is the area.
