Question

If the area of the foue walls ct a room is 88 sq.m. and the parimeter of its flooe is 22m. then the height of the room is

Answer 1

Given, perimeter of the rectangle = 22 m

2( length + breadth  ) = 22 m       ...( i )

Also given, area of four walls = 88 m²

2( length + breadth ) × height = 88 m²

From ( i ) value of 2( length + breadth ) is 22 m

22 m × height = 88 m²

height = $\dfrac{88\times m^{2}}{22 \times m }$

height = 4 m

Therefore, height of the room is 4m.

Answer 2

HERE IS YOUR SOLUTION

Given:-

perimeter of the rectangle = 22 m

We know that

Perimeter of rectangle=2(l+b)

so,

2(l+b)= 22 m.................( i )

NOW,

Area of four walls = 88 m²

2( l+ b) × h = 88 m²

From equation  (i) putting the value of 2(l+b)

22 m × height = 88 m²

height =88m²/22m

Height = 4 m

Hence,

Height of the room is 4m.
