the breath of a rectangular landscape is 6 times its length . there is a playground in it whose area is 4200 square mtr & which is 1 / 7 th of the total landscape . what is the breath of the landscape ?
"sol . 6 x * x = 7 * 4200 x = 70 length = 6 * 70 = 420 b"
multiply(sqrt(divide(multiply(4200, 7), 6)), 6)
