Find the area of triangle whose base measures 22 cm and the corresponding height measures 18 cm.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 198 cm2
A triangle is half of a parallelogram with the same base and height, so its area is \(\frac{1}{2}\times\text{base}\times\text{height}\), where the height is the one drawn to that base.
Half of base times height: \(\displaystyle\frac{1}{2}\times22\times18\)
\(11\times18=198\), so the area is 198 cm2
