Question

The perimeter of an isosceles triangle is $0.64m$ and its base measures $0.24m$. Find the length of equal sides in $cm$

Answer 1

To find the length we need to use the perimeter of the triangle

Let equal sides $=am$

then the perimeter of the triangle $=Sumofallsides$

$$\begin{gathered} 0.64=0.24+a+a \\ 0.64=0.24+2a \\ 2a=0.64-0.24 \\ 2a=0.40 \\ a=\frac{0.40}{2} \\ a=0.20 \end{gathered}$$

Hence the equal sides of the triangle is $0.20m$
