Question

Area of triangle with base 3cm and height 8cm is 12cm^2.




True

False​

Answer 1

➠true,

➠yes it is true.

explanation

➠area of tringle = 1/2*base*height.

➠1/2*3*8

➠1/2*24

➠24/2

➠12cm^2.

➠so, it is true.

hope it's helps you

Answer 2

Step-by-step explanation:

Question:-

Area of the triangle with base 3cm and height 8cm is 12cm².

True or false ?

Answer:-

To find whether the sentence is true or not,we have to perform the sum ourselves.

Let's do it !

Given:-

• The given figure is a triangle.

• The base of the triangle is 3cm.

• The height of the triangle is 8cm.

To find:-

Area of the triangle

Process:-

As we all know that,

$Area \: of \: triangle \: = \frac{1}{2} × Base × Height$

Inserting the above value in the formula:-

$⇒Area \: of \: triangle = \frac{1}{2} × 3 \times 8 \\ \\ ⇒Area \: of \: triangle = 4×3 \\ \\ ⇒Area \: of \: triangle = 12cm²$

∴ We can see that our answer is the same as the answer given in question.

Thus,the sentence is true.
