2) A builder is tiling a new bathroom and requires 30 tiles which are of
length z and height y. Find an equation that would show the area of the tiled
parts of the bathroom in terms of x and y.

Answer 1

30xy

Explanation:

Area for rectangle is length * width

____________________________________

Given

length of tile = x

width of tile = y (here y is given as height , it can be considered as width)

area of one tile = x*y = xy

there are 30 tiles used

thus area of 30 tiles = 30* area of one tile = 30xy

Thus, area of tiled parts is 30xy
