the total area of bed room will be 2( lh+hb) if h ,l , b are height ,length & breadth respectively.
now we know the perimeter of room ie 2 (l +b) = 220 .. ie (l + b) = 110
now total area .... 2 ( lh + bh) = 2 h ( l + b) ....taking h common
substituing for value of h and (l + b) ......ie 2 x 12 x 110 = 2640 sq.ft
but 1 sheet cover area of 220 sq.ft
therefore no.of sheets required = total area / area of 1 sheet
= 2640/220 = 12 sheets
the no. of sheets required = 12 sheets

How can you calculate a triangles perimeter given only the height?
To calculate a triangle's perimeter, you need more information than just the height. The perimeter is the sum of all three sides, so knowing only the height does not provide enough data. If you also know the base or any other side lengths, you can use the height in relation to them to find the perimeter. Otherwise, additional information about the triangle is necessary to determine the perimeter accurately.
Can you find the height of a triangle when you know the perimeter?
No.
