s+s+s+s*3/2 * * * * * No, that is not true. A rhombus is like a skewed square: it has four sides which are of equal length r. The perimeter is, therefore, r+r+r+r = 4*r
Let R = % rateEquation: 52.5 = R * 7 7R = 52.5 divide the equatio n by 7 R = 52.5/7 R = 7.5 Multiply by 100% Thus; R = 750%
R = S + 2T S = 3T .... substitute R = (3T) + 2T R = 5T
