Answer to this question

Answer: The height of the rectangle is 8 centimeters (cm)
How?
A(rea) = B(ase) × H(eight)
Since the question gives us the formula (A = B × H), area (120 cm), and base (15 cm), it fills in some parts of the equation.
So really:
120 = 15 × H <-- This is the formula, but some parts are filled in
Which can be rearranged as:
H = 120 ÷ 15 <-- Solve this
H = 8
Hope this helps.
