Answer:

x=12 Hope this helps!!!

Step-by-step explanation:

Remember a straight line equals 180 and when you have the box the angle is 90 degrees. Try solving the equation 5x-22+4x+4+90=180.

5x-22+4x+4+90=180 (combine like terms)

9x+72=180 (subtract 72 from both sides)

9x=108 (divide 9 on both sides)

x=12

Length of a rectangle is four times its width. If the perimeter is 100 m, what is the area in square cm?

melisa1 [442]

Set the width to be x. Thus, the length is 4x.

The perimeter is 2(x+4x)=100, so x=10.

Plugging in x=10, you get that 4x=40.

So, the area of the rectangle is 400 $m^2$ .

Because there are 100 centimeters in a meter and you are asking for area, you must multiply by $100^2$ to get 4000000 $cm^2$ .
