that is the area of rectangle is incorrectly written and should be written as "rectangle area" being its meaning:
It is the surface of this geometric shape that is rectangular but not square because two equal and parallel sides are unequal with respect to the other two also equal length and parallel. Its area formula is base height, i.e. what measured multiplied aside so it measures one of its contiguous. For those who know little geometry edges must be expressed in the same measure of length by multiplying; We can not multiply centimeters meters; Yes meters meters or centimeters with cm. They are Perogrullo truths, but we must remember them.
