Question

what is the area of a triangle that has a base of 4 cm and a height of 10 cm ?​

Answer 1

Step-by-step explanation:

he first thing we should note here is that we are looking for the area, so we need to recall the formula for the area of a right-angled triangle:

he first thing we should note here is that we are looking for the area, so we need to recall the formula for the area of a right-angled triangle:Area = (base x height) / 2

he first thing we should note here is that we are looking for the area, so we need to recall the formula for the area of a right-angled triangle:Area = (base x height) / 2Next we can input our values given in the question, into the formula:

Answer 2

Given:-

• Base of triangle is 4 cm.
• Height of triangle is 10 cm.

To find:-

• Area of triangle.

Solution:-

We know that

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

In which,

• b is base of triangle
• h is height of triangle

➢ Base = 4 cm

➢ Height = 10 cm.

So, Put the base and height in above formula

$\implies \sf \frac{1}{2} \times 4 \times 10$

$\implies \sf \frac{1}{2} \times 40$

$\implies \sf \frac{40}{2}$

$\implies \sf 20$

Therefore,

Area of triangle is 20 cm².
