Question

wall 4.84 m long and 3.1 m high is covered with rectangular tiles of size 22 cm by 10 cm. Find the total cost of the tiles at the rate of $1.50 per tile.​

Answer 1

ɢɪᴠᴇɴ :

• length of the wall is 4.84 m
• breadth of the wall is 3.1 m
• size of tiles is 22 cm by 10 cm
• cost of 1 tile is ₹1.50

ᴛᴏ ғɪɴᴅ :

• the total cost of all tiles

sᴏʟᴜᴛɪᴏɴ :

Area of wall = length x height

= 4.84 x 3.1

= 15.004 m²

= 15.004 x 10,000

= 150040 cm²

Area of one tile = 22 x 10

= 220 cm²

∴ Number of tiles = $\sf{\frac{( Area\: of \:the\: wall )}{( area\: of \:1 \:tile)}}$

= $\sf{\frac{150040}{220}}$

= 682 tiles

Cost of 1 tile = ₹ 1.50

∴ Cost of 682 tiles = 682 × 1.50 = ₹1023
