36 is the first number with 3 6 and 9 as common factors. thereafter you add 18 which is the smallest common factor for 3 6 and 9 therefore 36 54 72
18 Remember 6 x 3 = 18 9 x 2 = 18
Perimeter = 2*(L + B)So 30 = 2*(9 + B)15 = 9 + B so that B = 6And therefore, Area = L*B = 9*6 = 54 sq metres.Perimeter = 2*(L + B)So 30 = 2*(9 + B)15 = 9 + B so that B = 6And therefore, Area = L*B = 9*6 = 54 sq metres.Perimeter = 2*(L + B)So 30 = 2*(9 + B)15 = 9 + B so that B = 6And therefore, Area = L*B = 9*6 = 54 sq metres.Perimeter = 2*(L + B)So 30 = 2*(9 + B)15 = 9 + B so that B = 6And therefore, Area = L*B = 9*6 = 54 sq metres.
11 1/3 + 6 7/9= 11 1x3/3x3 + 6 7/9= 11 3/9 + 6 7/9= 17 10/9= 18 1/9
