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

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 .

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

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
