Annette wanted to buy new carpet for her L-shaped room. Which two expressions could be used to calculate the area of her room?

Which expressions?

A.

(17 • 6) + (20 • 10)

B.
(17 • 20) – (14 • 10)

C.
(17• 6) + (14 • 10)

D.
(17 • 20) – (7 • 14)

To calculate the area of Annette's L-shaped room, we need to break it down into smaller, simpler shapes. Let's assume the L-shaped room can be divided into a rectangular portion and a triangular portion.

1. Expressions for the rectangular portion:
To calculate the area of a rectangle, we multiply the length by the width. Let's say the length of the rectangular portion is L1 and the width is W1. The expression to calculate the area of the rectangular portion would be: Area_rectangular = L1 x W1.

2. Expressions for the triangular portion:
To calculate the area of a triangle, we multiply the base by the height and divide by 2. Let's say the base of the triangular portion is B2 and the height is H2. The expression to calculate the area of the triangular portion would be: Area_triangular = (B2 x H2) / 2.

Therefore, the two expressions that could be used to calculate the area of Annette's L-shaped room are:
1. Area_rectangular = L1 x W1 (for the rectangular portion)
2. Area_triangular = (B2 x H2) / 2 (for the triangular portion)
