To find the area of the garage door on the blueprint, we need to multiply the area of the actual garage door by the square of the scale factor. The area of the garage door on the blueprint is 0.55 ft².

To find the area of the garage door on the blueprint, we need to multiply the area of the actual garage door by the square of the scale factor. The scale factor is 0.05, so the area of the garage door on the blueprint can be found by multiplying 0.05 by 0.05 and then multiplying that product with the area of the actual garage door, which is 220 ft².



Area of the garage door on the blueprint = (0.05)² * 220 ft² = 0.0025 * 220 ft² = 0.55 ft²



Therefore, the area of the garage door on the blueprint is 0.55 ft².
