⇒⇒⇒⇒⇒Sid was given the following enlargement of a rectangle. A smaller rectangle with length of 8 feet and width of 4 feet. A larger rectangle with length of blank and width of 20 feet. Sid calculated the scale factor to be One-fifth. What error, if any, did Sid make when he calculated the scale factor? Sid found the reciprocal of the scale factor. Sid used the wrong dimensions to calculate the scale factor. He should have gotten Five-halves as the scale factor. Sid used the wrong dimensions to calculate the scale factor. He should have gotten Two-fifths as the scale factor. Sid did not make an error calculating the scale factor. The correct scale factor is One-fifth. WILL MARK BRAINLIEST
