Final answer:
To find the enlarged length of a rectangle when scaled by a factor of 8, multiply the original length (6 cm) by 8, resulting in an enlarged length of B.48 cm.
Step-by-step explanation:
The question asks to calculate the enlargement of the length of a rectangle when the scale factor is 8. The original length of the rectangle is 6 cm. To find the length of the enlargement, multiply the original length by the scale factor.
Enlarged length = Original length × Scale factor
Enlarged length = 6 cm × 8
Enlarged length = 48 cm
Therefore, the length of the enlargement is 48 cm, which corresponds to option B.
