Gina is cutting construction paper into rectangles for a project. She needs to cut one rectangle that is 12 inches by 14 1/4 inc
Fittoniya [83]

Answer:

278.63 square inches

Step-by-step explanation:

Gina needs to cut two types of rectangles.

Dimensions of one rectangle is given as,

Width = 12 inches

Length = 14\frac{1}{4} = \frac{57}{4} inches

So, the area of this rectangular paper will be

Area = width × length = 12\times \frac{57}{4} = 171 inches²

Dimensions of the other rectangular paper has been given as

Width = 10\frac{1}{4} = \frac{41}{4} inches

Length = 10\frac{1}{2} = \frac{21}{2} inches

So, the area of this rectangle will be

Area = width × length = \frac{41}{4} \times \frac{21}{2} = 107.63 inches²

Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.
