10. Kenny drew a scale drawing of a swimming pool . The scale of the drawing was 2 centimeters: 1 meter. If the pool is 26 centimeters in the drawing, how wide is the actual pool?​

answer: 20

step-by-step explanation:

you can use a^2+ b^2=c^2

to find the perimeter, you add up all the lengths of the sides. in this case you would have to add up 18+22+40+80 which equals 160.

step-by-step explanation:

consider the parallelogram shown in the attached image.

in the parallelogram hijk, the length of hk is given as,

from the properties of parallelogram we know that the opposite sides of a parallelogram are parallel to each other and are equal in measure.

therefore, the length of the side ij must be equal to the length of the side hk and that is .

hence, the expression for the length of ij confirms that hijk is a parallelogram.
