Answers
Answer:
Total money she has to spend will be = Rs.18600/-
Step-by-step explanation:
Given that : L = 16m and B = 12m
Let us convert it in cm. therefore L = 16 x 100 = 1600cm
B = 12 x 100 = 1200cm
From the measures we know that it is a rectangle.
Area of the rectangular hall = L x B
= 1600 x 1200
= 1,920,000sqcm
Now the sides of the Square tile is = 40cm
Area of Square tile = side x side
= 40 x 40
= 1600sqcm.
No. of Tiles required to cover the hall will be = Area of Rectangular hall
Area of Square tile
= 1920000/1600
= 1200 tiles
Total cost to cover the hall with tiles will be = 1200 * 15.50
= Rs.18,600/-
