Question from Pauline, a parent: A rectangle has an area of 27 squared inches. the height is 3 times the base |
Hi Pauline,
The area of a rectangle is the length times the width. This question calls the length "height" and the width "base" so if you let h be the height in inches and b the base in inches then the first sentence says
h × b = 27
The second sentence says that h is 3 time b, that is
h = 3 × b
Substitute 3 × b for h in the first equation which results in an equation for b. Solve for b and then find h from h = 3 × b.
