Question

A wall 5m long 3m high is covered with rectangle tiles of size 25cm by 15cm find the cost of the rate of 12.50 per tile​

Answer 1

Step-by-step explanation:

$area \: of \: the \: wall = 5m \times 3m = 15m$

$area \: of \: 1 \: tile = 25cm \times 10cm = 250cm$

$the \: uses \: of \: tiles \: = \frac{1500}{250} = 6$

$the \: cost \: of \: 6 \: tiles \: at \: rate \: of \: 12.50 \: of \: per \: tile \: = 12.05 \times 6 = 75$
