A rectangle has an area of 100 cm². The base of the rectangle is 25 cm. What is the height of the rectangle? A) 4 cm b) 10 cm c) 76 cm D) 2400 cm

Hope you know that base and height are qualities of a 3D figure, not 2D ones like rectangles. The correct terms are length and width.

Area=Length x width

So we have

100=25 * width 100=25 * width

And thus we use division

Width = 100:25=4 100:25=4

So the width of the rectangle is 4 cm.
