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
