Answer:
The original dimensions are 4.8 cm and 6.4 cm.
Step-by-step explanation:
Original dimension (Width): x
Original Dimension (Length): y
Find the original width given the new measurement 19.2 cm:
4x = 19.2cm
4x / 4 = 19.2/4
x = 4.8 cm
Find the original length given the new measurment 25.6 cm:
4y = 25.6
4y / 4 = 25.6/4
y = 6.4 cm
The original dimensions are 4.8 cm and 6.4 cm.
