Question

Find the area of the triangle below.Carry your intermediate computations to at least four decimal places. Round your answer to the nearest tenth.15 yd13 ydIl yd?16 yd

Answer 1

First we need to find the semi-permiter

`s=(a+b+c)/(2)`

where a,b,c are the sides of the triangle

a=15

b=16

c=13

`s=(15+16+13)/(2)=22`

Then we will use the Heron's formula in order to find the area of the triangle

`A=\sqrt[]{s(s-a)(s-b)(s-c)}`

then we substitute the values
