Given is triangle with base = 10 cm and perpendicular height = 3 cm.
We know the formula for area of triangle is given by :-
Area = [tex] \frac{1}{2} [/tex] × (Base) × (perpendicular height)
Area = [tex] \frac{1}{2} [/tex] × (10) × (3)
Area = [tex] \frac{30}{2} [/tex]
Area = 15 cm²
So, final answer is 15 cm².
