hey mate here's ur ans
total surface area of cuboid = 50 m²
=> 2(lb + bh + hl) = 50
=> 2lb + 2bh + 2hl = 50 .......(1)
lateral surface area of cuboid = 36 m²
=> 2lh + 2bh = 36. .......(2)
putting (2) in (1),
2lb + 36 = 50
2lb = 50 - 36
2lb = 14
lb = 14/2
lb = 7
so, area of base = lb = 7m²
total surface area of cuboid = 50 m²
=> 2(lb + bh + hl) = 50
=> 2lb + 2bh + 2hl = 50 .......(1)
lateral surface area of cuboid = 36 m²
=> 2lh + 2bh = 36. .......(2)
putting (2) in (1),
2lb + 36 = 50
