The total amount of paper needed by Cara for the project is 390.9 inch².

Step-by-step explanation:

Dimensions of the 1st rectangle is 20 inches × inches

That is, the dimensions are 20 inches × inches

As, Area of a rectangle = Length × Width

So, we have,

Area of the 1st rectangle =

i.e. Area of the 1st rectangle =

i.e. Area of the 1st rectangle = 285 inch²

Further, it is given that,

Dimensions of the 2nd rectangle is inches × inches

That is, the dimensions are inches × inches

Then, we get,

Area of the 2nd rectangle =

i.e. Area of the 2nd rectangle =

i.e. Area of the 2nd rectangle = 105.9 inch²

Thus, the total area of the rectangles = 285 + 105.9 = 390.9 inch²

Hence, the total amount of paper needed by Cara for the project is 390.9 inch².
