Question

find the length of the of a triangle whose area is 25cm2 and altitude is 10cm

Answer 1

Step-by-step explanation:

area = 1/2 × base × height

25 = 1/2 × base× 10

base = 10 cm

Answer 2

5cm is the length of a triangle.    

Step-by-step explanation:

Given:

The area =25cm²

The altitude =10cm.

To find:

The length of a triangle.

Solution:

For a triangle, we need length and height.

In the sum altitude that is the height is specified and the area of the triangle is specified we need to find out the base of the triangle is the length of the triangle.

The area of a triangle is defined as the product of the altitude and the length gets divided by 2.

Area of triangle= (length×altitude)

                                         2

Substituting the values of Area=25cm² and Altitude=10cm in formula we get,

25cm² = (Length×10)

                      2

Length×5= 25cm

Length=$\frac{25}{5}$cm

Length(base)=5cm

Hence,

The base of a triangle is 5cm.
