Question

marcos is making shapes out of paper for a geometry project. how many square centimeter fabric will marcos need to make the paper shape below? marcos will need square centimeters fabric to make the paper shape.

Explanation:

Step1: Calculate the area of the lower rectangle

The formula for the area of a rectangle is \(A = l\times w\). For the lower rectangle, \(l = 12\) cm and \(w = 4\) cm. So, \(A_1=12\times4 = 48\) \(cm^{2}\).

Step2: Calculate the area of the upper rectangle

The width of the upper rectangle is \(3\) cm. The height of the upper rectangle is \(8 - 4=4\) cm. Using the area formula \(A = l\times w\), \(A_2 = 3\times4=12\) \(cm^{2}\).

Step3: Sum the areas of the two rectangles

The total area \(A=A_1 + A_2\). Substitute \(A_1 = 48\) and \(A_2=12\) into the equation: \(A=48 + 12=60\) \(cm^{2}\).

Answer:

60
