Answer:
1500 cm²
Step-by-step explanation:
The length of the paper - 60 cm
The breadth of the paper - 40 cm
We can see that 5 cm is cut from all around the paper, this means the paper decreases in length by 5+5=10 cm and the breadth also decreases by 5+5 =10 cm. This is because the 5 cm width paper is cut as a border all over the paper.
New length = 60-10 = 50 cm
New breadth = 40-10 = 30 cm
The area of the paper = 50 X 30 = 1500 cm²
