Answer 1

Hi

Here is ur answer

==============================================================

Given

l = 20 cm  

b = 16 cm

Areas of floor and flat roof = sum of areas of the four walls

2 (lb) = 2 (l + b) h

2 (20) (16) ) = 2 (20 + 16) h

640 = 72 h

72 h = 640

h = 640/72

h = 8.89

==============================================================

Hope it helps U
