Question

Find the perimeter (or circumference) and area of the figure. (Where necessary, use 7= 3.14.)

Answer 1

This is a Triangle. The perimeter of a triangle is given by the sum of all sides:

`\begin{gathered} P=a+b+c \\ a,b,c=\text{the sides of the triangle} \\ a=5,b=5,c=6 \\ P=5+5+6=16 \\ P=16units \end{gathered}`

Area of triangle is given by 1/2 * bh

`\begin{gathered} A=(1)/(2)bh+(1)/(2)bh(For2\text{Triangles)} \\ \Rightarrow A=bh \\ b=6,h=4 \\ A=6\cdot4=24 \\ A=24units^2 \end{gathered}`
