Question

Diameter of circle is 28 cm,height is 5cm.The area of triangle will be

Answer 1

$28 \times 5 = 140$

Answer 2

The area of the triangle $=35cm^{2}$

Step-by-step explanation:

Given,

The diameter of circle = 28 cm and the height(h) = 5 cm

To find, the area of triangle = ?

∴ The base of triangle(b) = $\dfrac{28}{2}$=14 cm

We know that,

The area of the triangle $=\dfrac{1}{2}\times b\times h$

$=\dfrac{1}{2}\times 14cm\times 5cm$

$=7cm\times 5cm$

$=35cm^{2}$

Hence, the area of the triangle $=35cm^{2}$
