Question

Mohan had a room. Length of a wall 9 feet, height is 10 feet, breadth is 10 feet. What is the Area of the only 3 walls with the height of the tiles in the room are 4 feet? ​

Answer 1

280 sq ft *

Step-by-step explanation:

there are two possibilities as under below:

area of three walls will either be (2bh+ hl) or (2hl + bh) .

height of tile = 4 ft

crucial point: the area of the three walls will either be divisible/multiple of the height/area of each tile adjusted in three walls .

possibile outcomes:

A1 = 2×10×10 + 10×9 = 290

A2 = 2×10 × 9 + 10×10 = 280

here 280 is divisible by 4( height of each tile)

possibly area = 280 sq. ft
