Question

If a triangle has a base of 43/4 cm and height of 63/4, what is its area

Answer 1

The Area of a triangle is calculated by

$\frac{1}{2} \times base + hight$

Given :-
$base = \frac{43}{4} cm \\ and \\ hight = \frac{63}{4} cm$
Putting the values in the formula we get


$Area \: of \: the \: triangle \: \\ = (\frac{1}{2} \times \frac{43}{4} \times \frac{63}{4 })cm {}^{2} \\ \\ = ( \frac{2709}{32})cm {}^{2} \\ \\ = 84.65625 cm ^{2}$

Answer 2

Answer:

base of the triangle =43/4.

height of the triangle = 63/4.

area of triangle = ½×43/4×63/4 = 2709/32 =84.65645cm². (proved)
