WILL MARK BRAILIEST IF CORRECT A contractor is building a set of stairs out of concrete. each stair is exactly the same length, width, and height. (a) witch solid figures can the stairs be broken into? what are the dimensions of each solid figure?
(b) how much concrete will be needed to form the stairs?

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.
