Answer 1

Answer:

Hope it will help you.

total area of the walls of a hospital ward =

Lateral surface area of cuboid

Answer 2

$\huge\mathbb{SOLUTION}$

$\implies\sf Area\;of\;hospital\;walls=2(l+b)h$

$\implies\sf 2(5+4)×2.5$

$\implies\sf 2×9×2.5$

$\implies\sf 45m^2$

Area of hospital walls = lateral surface area of cuboid
