Answer:
120 cm² or the same as the original
Step-by-step explanation:
The area of a rectangle is found using the formula A = l*w. The original rectangle is l = 20 and w = 6 so the area is A = 6*20 = 120 cm².
The rectangle is changed by "Double the width and halve the length" which means the l = 10 and w = 12. The area of this rectangle is A = 10*12 = 120 cm².
