Question

kylies backyard deck cost $85.00 per square meter to build. the deck is 8 meters wide and 12 meters long. how much did it cost to build the deck?

Explanation:

Step1: Calculate the area of the deck

The deck is rectangular. The area formula for a rectangle is \(A = length\times width\). Given \(length = 12\) meters and \(width=8\) meters. So \(A=12\times8 = 96\) square meters.

Step2: Calculate the total cost

The cost per square meter is \(\$85.00\). The total cost \(C\) is the product of the area \(A\) and the cost per - square - meter \(c\). Using the formula \(C = A\times c\), with \(A = 96\) and \(c = 85\). Then \(C=96\times85=(100 - 4)\times85=100\times85-4\times85=8500-340 = 8160\)

Answer:

\(8160\)
