Question

Help me I'm practicing

Answer 1

we calculate the area of one trangle and multiply by 2

we apply formula of the triangle area

`A=(b* h)/(2)`

where b is the base and h the height of the triangle

then replacing

`\begin{gathered} A=(6*5.2)/(2) \\ \\ A=15.6 \end{gathered}`

area of one triangle is 15.6square centimeters

Area of both triangles

`\begin{gathered} 15.6*2 \\ =31.2 \end{gathered}`

Area of the two triangle bases is 31.2 square centimeters
