The figure shows two squares and a shaded triangle. If the area of the triangle is 2 sq. units then what is the area of the larger square?
Based on the geometric relationship shown in the figure (the triangle's legs relate to the square's side via the diagonal), the area of the larger square works out to 8 sq. units when the triangle's area is 2 sq. units.
Re-check your working by substituting the answer back into the original question.
