Problem

Find the altitude of a right triangle that is dividing its base of 12 cm into 8 cm and 4 cm.

Given

A right triangle that is dividing its base of 12 cm into 8 cm and 4 cm.
Here x \$= 8 cm\$, and y \$= 4 cm\$.

Formula:

Altitude of a a right triangle is given by

\$ h = \sqrt{xy} \$

Step

Substiutute the values.

\$\Rightarrow h = \sqrt{(8)(4)} \$

Step

Simplify.

\$\Rightarrow h = 4\sqrt{2} \$

Step

Answer

The altitude of a right triangle that is dividing its base of 12 cm into 8 cm and 4 cm is \$ 4\sqrt{2} \$.
