Answer 1

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:

`\begin{gathered} A=A_r+4\cdot A_t \\ A=(l\cdot w)+4((b\cdot h)/(2)) \\ A=3.25\cdot3.75+4\cdot(0.75\cdot1.875)/(2) \\ A=12.1875+2.8125 \\ A=15 \end{gathered}`

Answer: the area of the tool is 15 square inches.
