The ratio of the areas of two squares, one having its diagonal double than the other, is
(a)2 : 1
(b)2 : 3
(c)3 : 1
(d)4 : 1
Answer
Answer (as printed): D
Explanation
Let the diagonals be $2 d$ and $d$. Then, ratio of their areas $=\frac{\frac{1}{2} \times(2 d)^{2}}{\frac{1}{2} \times d^{2}}=\frac{4 d^{2}}{d^{2}}=\frac{4}{1}=4: 1$.
