20/100 x 140 =(20/100) x 140 = 0.2 x 140 = 28

Answer:

294 in.²

Step-by-step explanation:

I believe this figure is a rectangular prism.

------------------------------------------------------------------------------------

Explain:

To find the surface area of a rectangular prism, use this formula:

$SA=2lw+2lh+2wh$

$SA=2(lw+lh+wh)$

$l-length$

$w-width$

$h-height$

A phrase I use to help remember this formula is:

LISA WILSON LOST HER WITCH HAT TWICE (2)

------------------------------------------------------------------------------------

Solve:

The length of this rectangular prism is 9 in.

This width is 10 in.

The height is 3 in.

Now, I will plug the numbers into the first formula.

$SA=(2*9*10)+(2*9*3)+(2*10*3)=294 in.^2$

------------------------------------------------------------------------------------

Conclude:

I, therefore, believe the area of this rectangular prism is 294 in.²

I need to know the area of this triangle and I would like to have an explanation because I dont know how to do it I know the for

Softa [21]

Answer:

18 square units

Step-by-step explanation:

When one side is vertical or horizontal, it is convenient to find the height from the opposite vertex to that side. It is generally an integer number of grid squares.

Here, the height is 4 -(-2) = 6. The base length is 1 -(-5) = 6. That means the area is ...

A = 1/2bh

A = 1/2(6)(6) = 18 . . . . square units

Alternate solution

If you want to go at this the hard way, you can find the length of LK and the distance of J to that line.

The length of LK is ...

d = √((x2 -x1)^2 +(y2 -y1)^2) = √((4 -(-2))^2 +(3 -(-5))^2) = √(36 +64) = 10

The distance to line LK can be found by writing the equation of the line LK in general form:

4x -3y -7 = 0

Then the distance formula for point (x, y) is ...

d = |4x -3y -7|/√(4^2 +3^2)

d = |4(-2) -3(1) -7|/5 = |-8 -3 -7|/5 = 3.6

Using the area formula with these dimensions gives ...

A = 1/2bh = 1/2(10)(3.6) = 18 . . . . square units
