Question
Find area of triangles
a. Whose height is 5cm and base is 10cm
b. Whose three sides are a = 5 cm, b = 5 cm and c = 8 cm
Hint:
In (a) simple use Area of triangle = and in (b) isosceles triangle is given.
The correct answer is: a) 25 cm2 , b) 12 cm2
(a) It is given that base, b = 5 cm and height, h = 10 cm
Area of triangle = = 25 cm2
(b) It is given that a = 5 cm , b = 5 cm and c = 8 cm
Now, using Heron’s formula
Area of triangle = where s =
s = = 9
Area of triangle =
=
