Question

find the area of triangle. whose base is 18cm and height is 15 cm​

Answer 1

Answer:

The area of the triangle, whose base is 18cm and height is 15 cm​ is 135 sq.cm.

Step-by-step explanation:

Given:

Base of triangle = 18 cm

And the height of a triangle = 15 cm

Find the area of the triangle.

Formula: Area of triangle = 1/2 × base × height

Area of triangle  = 1/2 × 18 × 15

= 9 × 15

= 135 sq. cm.

So, the area of the triangle is 135 sq. cm.

Answer 2

Answer:

Area of triangle is $135\ cm ^{2}$ .

Step-by-step explanation:

To find :  area of triangle.

Given :  base of triangle is 18cm and height is 15 cm​ .

Solution :

• As per given data we know that ,  base of triangle is 18cm and height is 15 cm​ .  We have to find area of triangle .
• Area of triangle is given by following formula by multiplying half with base and height ,
• Area of triangle = $\frac{1}{2} \times base \times height$

                                  $= \frac{1}{2} \times 18 \times 15 \\\\ = 9\times 15\\\\ = 135\ cm ^{2}$
