Answer:

8

Step-by-step explanation:

x+4=12, so 12-4=x (if you use an the inverse operation of addition, subtraction.)

12-4=x, so all you have to do is subtract and, there you have it, 8. It makes sense, 8+4=12. :)

Below is the proof why the area of a parallelogram is B times H

<h3>How to form a rectangle from the parallelogram</h3>

The following steps would create a rectangle from the parallelogram

  • Step 1: Cut out the triangular part of the parallelogram
  • Step 2: Attach the triangular part to the other end of the parallelogram

See attachment for the steps.

When the rectangle has been created, we have the following dimensions:

Length = h

Width = B

The area of a rectangle is:

Area = Length * Width

This gives

Area = h * B

Evaluate

Area = Bh

Hence, the area of a parallelogram is B times H

Answer:

126 inches

Step-by-step explanation:

If your drawing is on a 1 : 40 scale, to find the scale's height, divide the ride's height by 40.

420 / 40 = 10.5

So the drawing will be 10.5 feet tall.

To convert 10.5 feet to inches, multiply it by 12.

10.5 * 12 = 126 inches
