Question

3) Length and height of a wall is 5m and 7m respectively which is
covered with tiles of rectangular shape whose length and breadth is
10cm and 5cm respectively. Find the total cost of the tiles if each tile
is of cost ₹ 2.25.​

Answer 1

• area of rectangle =width×height length =5m height = 7m , 7×5=35 , perimeter of rectangle=2× l+b length = 10cm breadth = 5cm =2×10+5 =30 = 30+35 =65 , now each cost of tile is 2.25 ×65 =146.25
