Question

a rectangular portrait is 1 meter wide and 1 meter high. it costs $11.00 per meter to put a gold frame around the portrait. how much will the frame cost?

Explanation:

Step1: Calculate the perimeter of the portrait

The formula for the perimeter of a rectangle is \(P = 2\times (l + w)\). Here, \(l = 1\) meter and \(w = 1\) meter. So, \(P=2\times(1 + 1)\)
\(P = 4\) meters.

Step2: Calculate the cost of the frame

The cost per meter is \(\$11\). Multiply the perimeter by the cost per - meter. Let \(C\) be the cost. Then \(C=11\times P\). Substitute \(P = 4\) into the formula: \(C = 11\times4\)
\(C=\$44\)

Answer:

\(44\)
