Question

Find the altitude of a triangle whose area is 45cm² and base 15cm

Answer 1

Answer:

Hence, height / Altitude of triangle will be 6 cm

Step-by-step explanation:

In context to question asked,

We have to determine the altitude / Height of triangle.

As per data given in the question,

We have,

Area of triangle = 45 Sq. cm

Base of triangle = 15 cm

As we know that,

Triangle is a three sided figure,

Sum of all angles of the triangle is 180 degree.

The area of triangle can be determined by using formula $Area = \frac{1}{2} \times base \times Height$

So, for determining the height of triangle we will put the value of base and area given in the question in above formula,

Thus we will get it as,

$Area =\frac{1}{2} \times b \times h\\=>45 = \frac{1}{2}\times 15 \times h\\=>h = \frac{45 \times 2}{15}\\=>h = 3\times 2 = 6\:cm$
