Ответ:
the answer is A. 18 inches
Ответ:
A:18 inches
ExplanationTo solve this, we just need to find the length of the median of the trapezoidal tiles. Remember that the length of the median of a trapezoid is half the sum of the length of the bases.
We know from our problem that the bases of our trapezoid are 15 inches and 21 inches long, so the median of our trapezoid is:
We can conclude that John will need to cut 18 inches so he cuts the tiles along the median.
