Question 37On a map whose scale is $400$ miles to an inch and a half, a certain estate is represented by a rhombus having a $60^\circ$ angle. The diagonal opposite $60^\circ$ is $\dfrac3{16}$ in. The area of the estate in square miles is:$\dfrac{2500}{\sqrt3}$$\dfrac{1250}{\sqrt3}$$1250$$\dfrac{5625\sqrt3}{2}$$1250\sqrt3$
