Question

Estimate the area of the shaded region. each square represents 20 in

Answer 1

1st. Let's find the area of the grid:

Each square represents 20 in². There are 45 squares, so:

`A=20\cdot45=900in^2`

The area of the shaded region will be the area of the grid minus the area of the number of squares which are not shaded, so:

`\begin{gathered} A_s\approx900-(15\cdot20) \\ A_s\approx900-300 \\ A_s\approx600in^2 \end{gathered}`
