A playground, which measures 60m by 40m, is to be doubled in area by extending each side of the playground by an equal amount. Determine how much eash side should be extended.
A playground, which measures 60m by 40m, is to be doubled in area by extending each side of the playground by an equal amount. Determine how much eash side should be extended.
the original area is 60*40 = 2400 cubic meters
Let the length each side is extended by be .
Thus the new area is given by:
we are told that with this extension, the area is doubled. thus we have,
