Question

What is the area of a triangle with base 12 cm and height 5.6 cm​

Answer 1

Answer :-

• The area of the triangle is 33.6 cm²

Given :-

• The base of the triangle = 12 cm.
• The height of the triangle = 5.6 cm.

To find :-

• The area of the triangle.

Step-by-step explanation :-

• Here, the base and height of a triangle have been given to us. We have to find it's area.

We know that :-

$\underline{\boxed{\sf Area \: of \: a \: triangle = \dfrac{1}{2} \times Base \times Height}}$

Here,

• Base = 12 cm.
• Height = 5.6 cm.

Hence,

$\rm Area = \dfrac{1}{2} \times 12 \times 5.6$

Reducing the numbers,

$\rm Area = \dfrac{1}{1} \times 6 \times 5.6$

Now let's multiply the remaining numbers since we can't reduce them anymore.

$\rm Area = 1 \times 6 \times 5.6$

Multiplying the numbers,

$\overline{\boxed{\rm Area = 33.6 \: cm^2}}$

Perimeter of a square :-

• $\sf4 \times Side$

Area of a square :-

• $\sf Side^{2}$

Perimeter of a rectangle :-

• $\sf2 \: (Length + Breadth)$

Area of a rectangle :-

• $\sf Length \times Breadth$

Perimeter of a triangle :-

• $\sf Sum \: of \: all \: the \: sides$

Area of an equilateral triangle :-

• $\sf\dfrac {\sqrt{3}}{4}(Side)^2$

Area of a scalene triangle :-

• $\sf \sqrt{s \: (s - a) \: (s - b) \: (s - c)}$
