Ginny is cutting construction paper into rectangles. She needs to cut one rectangle that is 16 inches × 13 1/4 inches. She needs
kykrilka [37]

Answer:

317.92 square inches

Step-by-step explanation:

Rectangle A:

Area of a rectangle = length × width

Length = 16 inches

Width = 13 1/4 inches = 53/4 inches

Area of a rectangle = length × width

= 16 inches × 53/4 inches

= (16 * 53) / 4 inches²

= 848/4

= 212 square inches

Rectangle B:

Area of a rectangle = length × width

Length = 10 1/3 inches = 31/3 inches

Width = 10 1/4 inches = 41/4 inches

Area of a rectangle = length × Width

= 31/3 inches × 41/4 inches

= (31 * 41) / (3 * 4) square inches

= 1271 / 12

= 105.92 square inches

How many total square inches of construction paper does Ginny need?

total square inches needed = Area of rectangle A + Area of rectangle B

= 212 square inches + 105.92 square inches

= 317.92 square inches
