It can also be solve in a basic way the
Area =1/2 chase x height

It is obvious the hypothalamus is 5cm and the 4 and 3 are the base or and height( Pythagoras triple)

So area =1/2 x4x3=6cm²

thanks

Mrshape:


question 3 calculate the area of a triangle of sides 4cm 3cm and 5cm respectively

using heron's formula;

s = (a+b+c)/2
s = (4+5+3)/2 = 6

Area = √{s(s-a)(s-b)(s-c)} = √(6(6-4)(6-5)(6-3)) = 6cm²

Nice thread
