Answer :
We can calculate the area of the tool by dividing it in parts and then sum the areas of the parts.
We will use the divisions already set:
- One rectangle with sides l = 3.25 in and w = 3.75 in.
- Four right triangles with height h = 0.75 in and base b = 3.75/2=1.875 in.
Then, we can calculate the area of the tool as the sum of the area of the rectangle and the area of the 4 triangles:
[tex]\begin{gathered} A=A_r+4\cdot A_t \\ A=(l\cdot w)+4(\frac{b\cdot h}{2}) \\ A=3.25\cdot3.75+4\cdot\frac{0.75\cdot1.875}{2} \\ A=12.1875+2.8125 \\ A=15 \end{gathered}[/tex]Answer: the area of the tool is 15 square inches.
