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 more than 80 square centimeters. less than after 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 has dimensions 5 cm by 9 cm and the other has dimensions 5 cm by (6 + 3) cm.

Step2: Calculate area of first rectangle

The area of a rectangle is given by $A = l\times w$. For the first rectangle with length $l = 9$ cm and width $w = 5$ cm, $A_1=9\times5 = 45$ $cm^2$.

Step3: Calculate area of second rectangle

For the second rectangle with length $l = 5$ cm and width $w=(6 + 3)=9$ cm, $A_2 = 5\times9=45$ $cm^2$.

Step4: Calculate total area

The total area $A = A_1+A_2$. So $A=45 + 45=90$ $cm^2$.

Answer:

90 square centimeters
