Answer: No change in the area ; it will remain same. Step-by-step explanation: Area of the rectangle = length × breadth = 18 × 8 = 144 cm^2 New length = 2/3 × 18 = 12 cm New breadth = 3/2 × 8 = 12 cm So, New Area = New length × New breadth = 12 × 12 = 144 cm^2 Hence, the area will remain same. It will not change. Hope it helps u !!!!!!! Reply
Answer:
No change in the area ; it will remain same.
Step-by-step explanation:
Area of the rectangle = length × breadth = 18 × 8 = 144 cm^2
New length = 2/3 × 18 = 12 cm
New breadth = 3/2 × 8 = 12 cm
So, New Area = New length × New breadth = 12 × 12 = 144 cm^2
Hence, the area will remain same. It will not change.
