okay so you should know that the formula for a triangle is:

A=1/2×b×h

where b is breadth and h is height

A is area

so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)

so we put these into the equation of the area of a triangle

A=1/2×b×h

16.2=1/2 × 6 × h

then you will solve algebraically to get 5.4cm which is you answer

to check if correct you can always put in all numbers in equation and you should get 16.2cm

In this case it's correct ✌

Answer:

AC = 5.4 cm

Explanation:

The area (A) of a triangle is calculated using the formula

A =
(1)/(2) bh ( b is the base and h the perpendicular height )

here AC is the base (b) and AB the height (h), thus


(1)/(2) × AC × 6 = 16.2

3AC = 16.2 ( divide both sides by 3 )

AC = 5.4 cm
