Answer:

(d) 588 square units

Explanation:

You can get the same answer a couple of ways.

1. Enlarge each of the dimensions by a factor of 3.5, then figure the area.

8 ⇒ 3.5×8 = 28

6 ⇒ 3.5×6 = 21

Area = LW = 28×21 = 588 . . . square units

__

2. Find the area of the given figure, and multiply that by the square of the scale factor:

Area = LW × (scale)² = (8×6)×3.5² = 48×12.25 = 588 . . . square units

_____

If you look carefully at the first calculation, you see it is identical to the second.

(8×3.5) × (6×3.5) = (8×6) × (3.5×3.5) = (8×6)×3.5²
