Question

find the a area of a triangle whose base is 10 and height is 20

Answer 1

$\implies$ Given, Base = 10 & height = 20

$\implies$ Apply, the formula

$\implies$ = 1/2 × base × height

$\implies$ =1/2 × 20× 10

$\implies$ =100 cm2

$\implies$ $\boxed{\textbf{answer \: is \: 100 cm}}$²

Answer 2

Answer:

Hence, area of triangle will be 100 Sq. unit

Step-by-step explanation:

In context to question asked,

We have to determine the area of triangle.

As per data given in the question,

We have,

Base of triangle = 10 units

Height of triangle = 20 units

As we know that,

Triangle is a three sided figure,

Sum of all angles of the triangle is 180 degree.

The area of triangle can be determined by using formula $Area = \frac{1}{2} \times base \times Height$

So, for determining the area of triangle we will put the value of base and height given in the question in above formula,

Thus we will get it as,

$Area =\frac{1}{2} \times 10 \times 20\\=>Area = 5 \times 20\\=>Area =100 \:unit^2$
