Question

The perimeter of the floor of a rectangular room is 17m and its length is 5 m . Find the cost of flooring the room with square tiles of side 25 cm at the rate of Rs 850 per hundred tiles

Answer 1

if p= 17and l=5 then b= 17-10=7÷2=3.5 .b=3.5 .if l=5 and b= 3.5, then area of rectangle =5×3.5=17.5 m sq . a of tiles =25×25=0.0625. no. of tiles = a of rectangle ÷a of tile . 17.5÷0.0625 =280m then 280 ×850/100 =2380

Step-by-step explanation:

given p is equal to 17m

l is equal to 5m

p,= 2(l+b)

17=2(5+b)

17=10+2b

17-10=2b

7=2b

7÷2=b

3.5=b

l=5

b=3.5

area =l×b

area=5×3.5

A=17.5
