Ans 1:

HARSHIT SOLANKI from Dps, Indore

Class : Class 6

area of 1 small rectangle = 3*2 =6 sq. cm.Total cards removed = 19 so ,19*6= 114 sq. cm.

Ans 2:

SHOURYA JANA from Birla High School Mukundapur, Kolkata

Class : Class 6

To solve this, let’s analyze the problem step-by-step: Find the area of a single small rectangle: Each small rectangle has a length of 3 cm and a breadth of 2 cm. So, the area of one small rectangle is: 3 cm × 2 cm = 6 sq. cm 3cm×2cm=6sq. cm Calculate the total area of all 81 small rectangles in the big rectangle: If there are 81 small rectangles, then the area of the big rectangle is: 81 × 6 sq. cm = 486 sq. cm 81×6sq. cm=486sq. cm Count the number of small rectangles remaining in the figure: From the image, we can count the number of small rectangles remaining. By visually inspecting, there appear to be 62 small rectangles left. Calculate the area of the remaining rectangles: With 62 rectangles remaining, the area of the remaining part is: 62 × 6 sq. cm = 372 sq. cm 62×6sq. cm=372sq. cm Find the total area of the rectangles removed: Subtract the area of the remaining rectangles from the total area to find the area of the removed rectangles: 486 sq. cm − 372 sq. cm = 114 sq. cm 486sq. cm−372sq. cm=114sq. cm Thus, the total area of the rectangles removed is 114 sq. cm. The correct answer is B) 114 sq. cm.

I put the answer already and when I was submitting it it said I did not complete the question, but I did and I know it because I did work for every problem on a separate sheet of paper and the correct answer matched the answer I put on my paper. I didn't forget to put the correct answer on the computer because I double checked all the questions if they were answered or not.
