Question

what is the area of a triangle if the base is 5 cm and the height is 3 cm​

Answer 1

$\frac{15}{2}$Answer:

base = 5cm

height = 3cm

Area of triangle =  $\frac{1}{2}$ × b × h

                          =  $\frac{1}{2}$ × 5 × 3

                          =  $\frac{15}{2}$ = 7.5 cm  ( By cutting )

Answer 2

Answer:

The area of a triangle = 7.5 cm²

Given:

What is the area of a triangle if the base is 5 cm and the height is 3 cm?

Step-by-step explanation:

Here we will simply use the formula of area of triangle to find its area. Putting values in the formula and doing basic mathematical calculations we can easily find out the area of a triangle.

♦ Area of a triangle = 1/2 × b × h

Where,

b is the base of a triangle.

h is the height of a triangle.

Putting the values in the formula, we have:

• Area of a triangle = 1/2 × 5 × 3
• Area of a triangle = 15/2
• Area of a triangle = 7.5 cm²

Therefore,

Area of a triangle = 7.5 cm²
