A contractor builds and installs custom-made railing material for $45 per square metre. How much will it cost to replace the railings?
We already worked out the area of the railings to be 7.68 square meters. Do you know what we have to do with this number to get the price for all 7.68 square meters at $45 per square meter?
Just take a guess. Give it your best shot.
Very close. We have to multiply. So we get that the total price would be \[7.68 \;\;\text{m}^2 \times 45\;\; {\text{dollars} \over \text{m}^2}=$345.6\] Sorry for the slow responses. It's lagging terribly on my end.
