Explanation:

the area of a triangle is

baseline × height / 2

baseline and height must be at a right angle with each other.

so, in our case

6 × 11 / 2 = 3 × 11 = 33 cm²

Answer:

Area = 33 cm²

Explanation:


\textsf{Area of a triangle}=\sf (1)/(2)bh

where:

  • b is the base
  • h is the height (perpendicular to the base)

If we turn the triangle counterclockwise, so that the side that measures 6 cm is the base, we will see that the length that measures 11 cm is the height of the triangle (see attached).

Therefore:

  • b = 6 cm
  • h = 11 cm

Substitute the found values into the formula and solve for A:


\implies \sf A=(1)/(2)(6)(11)


\implies \sf A=(1)/(2)(66)


\implies \sf A=33

Therefore, the area of the triangle is 33 cm²
