The discussion focuses on calculating the area of a white stripe on a flag, identified as a parallelogram. To find the area, the formula A = base x height is used, with dimensions of 72 inches for the base and 8.5 inches for the height. Participants confirm that the area calculates to 612 square inches. A diagram is suggested as a helpful tool for understanding the problem. The conversation emphasizes the importance of identifying the correct measurements for accurate area calculation.

Re: Solving how many square inches with in a flag

The white stripe is a parallelogram, whose area is found by computing the product of the base and the height. Can your daughter identify the measures of the base and height?

the white area is essentially a parallelogram
to calculate the area of a parallelogram

A = base x height

A = 8.5 x 72 = 612 square inches
 

Thread 'Area of Overlapping Squares'

Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
