Question

Work out the area of this triangle

Answer 1

Step-by-step 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 2

Answer:

Area = 33 cm²

Step-by-step explanation:

$\textsf{Area of a triangle}=\sf \dfrac{1}{2}bh$

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:

$\implies \sf A=\dfrac{1}{2}(6)(11)$

$\implies \sf A=\dfrac{1}{2}(66)$

$\implies \sf A=33$

Therefore, the area of the triangle is 33 cm²
