# Calculating Areas

Line segments are drawn from the vertices of the large square to the midpoints of the opposite sides to form a smaller, white square.

If each red or blue line-segment measures \(10\) m long, what is the area of the smaller, white square in m\(^{2}?\)

Suppose a square is cut by two parallel lines at perpendicular distance \(6\) cm. apart such that

(i) one line has an endpoint at the lower left corner of the square and the other has an endpoint at the upper right corner of the square, and

(ii) the square is divided into three regions, (a parallelogram and two triangles), of equal area.

What is the area of the square in cm\(^{2}\)?

There are 7 smaller squares inside the large rectangle above.

If the green square has side length 1 and the brown square has side length 2, what is the area of the rectangle?
