Asked by Heather M

If the sides of a square are increased by 3m, the area becomes 64m2. Find the length of a side of the original square.

A 4 m by 6 m rug covers half of the floor area of a room and leaves a uniform strip of bare floor around the edges. What are the dimensions of the room?

How about showing me what you got so far?

(X + 3)(X + 3) = 64

4 * 6 = .5X

For each problem, solve for X.

However, that only gives the floor area. There is no information about ceiling height.

I hope this helps. thanks for asking.
