The floor of a rectangle meeting room has a raised platform that is the same thing as room and it is 1/6 the width of the room. Estimate the area of the floor including the raised platform.

Areflection of shape i across the y-axis, followed by a , and then a translation left 6 units and down 4 units confirms congruence between shape i and shape ii. alternatively, a of shape ii about the origin, followed by a reflection across the y-axis, and then a translation right 4 units and up 6 units confirms congruence between shape ii and shape i.
