Answer 1

Ratio = 1:3   Let it be 3x and 1x Area = 3/4 3/4 = 3x × 1x  3/4 = 3x^2 3/12 = x^2 Root3/root12 = x Root3/2root3 = x x=1/2  1st side = 1x = 1 (1/2) = 1/2 2nd side = 3x = 3 (1/2) = 3/2 Perimeter = 2 (l+b)                   = 2 (1/2 + 3/2)                   = 2(4/2)                   = 2 (2)                   = 4 cm        Ans...   PLZZ...
