Question

mrs. goldstein is making shapes out of paper for a geometry project. how many square centimeters of fabric will mrs. goldstein need to make the paper shape below? the new area of the paper shape would be 80 square centimeters. a good estimate for the new area of the park would be square centimeters.

Explanation:

Step1: Divide the shape into rectangles

We can divide the given shape into two rectangles. One rectangle with dimensions 5 cm by 9 cm and another with dimensions 5 cm by 3 cm.

Step2: Calculate area of first rectangle

The area formula for a rectangle is $A = l\times w$. For the first rectangle with length $l = 9$ cm and width $w = 5$ cm, the area $A_1=9\times5 = 45$ square - centimeters.

Step3: Calculate area of second rectangle

For the second rectangle with length $l = 5$ cm and width $w = 3$ cm, the area $A_2 = 5\times3=15$ square - centimeters.

Step4: Calculate total area

The total area $A$ of the shape is the sum of the areas of the two rectangles, so $A=A_1 + A_2=45 + 15=60$ square - centimeters.

Answer:

60 square centimeters
