a + b + c = 36  cm

      surface area =   36 * 24 = ........ cm2     then divide by 10 000 to get m2

          

 

 1/2 b * h  =  54 

        b * h = 108

                           9 x 12  is a possible dimension

                           4 x 27      6 x 18    etc

a)   Surface area is:  A = (54 * 2) + (36 * 24) = 972 cm2 = 0.0972 m2

 

b)   Possible dimensions of the sides are:     9, 12, 15     (9+12+15=36) (92 + 122 = 152)
