Question

The 10 by 10 square shows an office floor plan composed of four congruent 8-sided cubicles. What is the area of one of these irregular 8-sided cubicles?

Answer 1

The side of the cubicle will be $\dfrac{10}{4} = 2.5$ and the area of one of the small parts will be $2.5^{2} = 6.25$ then the total area will be $6.25(8) = 50$ Hence the area of the irregular sides is 50 square unit.
