Q. Trapezoid KLMN is dilated by a scale factor of 41 to form trapezoid K'L'M'N'. Side L'M' measures 8. What is the measure of side LM?Answer:
Reverse Dilation Process: To find the measure of side LM in the original trapezoid KLMN, we need to reverse the dilation process. Since trapezoid K′L′M′N′ is a dilated version of KLMN with a scale factor of (1)/(4), we can find the length of side LM by dividing the length of side L′M′ by the scale factor.Calculation: LM=(1/4)L′M′
Substitute Given Value: Now we substitute the given value of L′M′ into the equation.Calculation: LM=(1/4)8
Multiply by Reciprocal: To divide by a fraction, we multiply by its reciprocal. So, we multiply 8 by the reciprocal of (1/4), which is 4.Calculation: LM=8×4
Perform Multiplication: Perform the multiplication to find the length of side LM.Calculation: LM=32
