Answer:
The total cost of the tiles is Rs 13392
Step-by-step explanation:
The length of the Rectangle = 41/2
The width of the rectangular floor = 64/4
The measurements of the rectangular tiles is given as :
Length = 1/2 feet
Width) 1/4 feet
From this we can get the rectangles that can fit along the length and width of the floor.
Along the length = 41/2 ÷ 1/2 = 41/2 × 2/1
= 41 tiles along the length.
Along the width we have = 67/4 ÷ 1/4 = 67/4 × 4/1 = 67 tiles.
Total tiles along the length and the width is given by :
= 2(67 + 41) ) = 216
We will need 16 tiles to cover the boundaries of the floor.
Each tile costs Rs 62.
The total cost of the tiles is given by:
= 62 × 216 = 13392
One needs Rs 13392 to tile the boundaries.
