Question from Mohammed:

I bought a 2 mm sheet plate of 1.2m × 2.4m in fijian $\$95.$ I used 1.95m × 0.4m from that sheet plate. What will be my total cost for the sheet plate I used. It was a mild steel plate.


1.2m by 2.4 m is $1.2 \times 2.4 = 2.88$ square meters. This cost you $\$95.$ so that's $\large \frac{95}{2.88} \normalsize = 32.99$ dollars per square foot. What is the square footage of the piece you used? At $\$32.99$ per square foot what is the value of the piece you used?
