given in this question...................


Total surface area of cuboid =2 x(length x breadth+breadth x height + height x length)=50'2m...... (1)

Lateral surface area of cuboid =2(breadth x height + height x length) =30 '2 m .......... (2)

difference (2) from (1)
2(length x breadth) =14 '2 m

length x breadth = 14 /2
7'2

Area of the base of cuboid =7 '2
