the diagonals of the two squares are in the ratio of 7 : 9 find the ratio of their area
let the diagonals of the square be 7 x and 9 x respectively . ratio of their areas = 1 / 2 ( 7 x ) ^ 2 : 1 / 2 ( 9 x ) = 49 x ^ 2 : 81 x ^ 2 = 49 : 81 answer ( c )
divide(divide(power(7, const_2), const_2), divide(power(9, const_2), const_2))
