length = 12m  ;  breadth = 8m ;  height = 5m

TSA of the tank = 2[length×breadth + breadth×height + height×length] = 2[12×8+8×5
+5×12]

 = 392m2

Area of the rectangular iron sheet = 392 m2

so, length × breadth = 392 ⇒ length = 392 / 2 = 196 m  [as sheet is 2 m wide]

Now total cost of the sheet = Rs. (196 × 50) = Rs. 9800

I hope it help you..☺️

Pratishtha2003: Here we should not find the tsa of tank but we should find lateral surface area and then add the product of given length and breadth as these are the dimensions of the base because the tank is opened at the top

Answer:

Length=12m,Breadth =8m,hieght=.5 m

TSA of the tank =2(lb+bh+lh)

2(12*8+ 8*5+ 5*12) =392cm²

Area of rectangular iron sheet =392m²

so,l*b =392

l=392/2 =196 m

now total cost of the sheet = 196*3.50 =686

the sheet =686/4 = 171.5 m²
