Question

find the area of a triangle whose base is 13cm and hieght is 20​

Answer 1

Answer:

130 cm^2

Step-by-step explanation:

area of triangle = 1/2×base×height

1/2×20×13

=10×13

=130

Answer 2

Given: The height of the triangle is $20$cm and the base of the triangle is $13$cm.

We have to find the area of a triangle.

As we know that the formula is used to calculate the area of the triangle is:

$A=\frac{h\times b}{2}$

Where,

h = height of the triangle

b = base of the triangle

We are solving in the following way:

We have,

$h=20cm\\b=13cm$

Now, the area of the triangle will be:

$A=\frac{h\times b}{2}$

$\Rightarrow A=\frac{20\times13}{2}\\\\\Rightarrow A=\frac{260}{2} \\\\\Rightarrow A=130$

Hence, the area of the triangle will be$130cm^{2}$
