Question

find the area of a triangle whose breadth is 5 centimetre and altitude is 4.5 CM​

Answer 1

Step-by-step explanation:

We know that

the area of a triangle with base b units and height h units is given by

A=\dfrac{1}{2}b\times h.

For the given triangle, we have

base, b = 5 cm and height, h = 4.5 cm.

Therefore, the area of the triangle is

A=\dfrac{1}{2}b\times h=\dfrac{1}{2}\times5\times4.5=5\times2.25=11.25~\textup{cm}^2.

Thus, the area of the triangle is 11.25 cm²
