To many people worldwide, excluding North America and Canada, the most familiar paper size is A4. It is the standard paper size for most home printers.



Question:1) If the largest square formed

by folding the A4 paper is again folded to form two triangles, what will be the area of each triangle

A)

B)

441 cm²

66.125 cm²

220.5 cm²​

Answer 1

Answer: 220.5$cm^{2}$

Step-by-step explanation:

• We need to find the area of largest square that can be made from A4 sheet of dimensions (210×297)mm.
• Area of square=(210×210)$mm^{2}$

                                 =44100$mm^{2}$

                                 =441 $cm^{2}$

• The area of triangle=$\frac{1}{2}*Area \ of\ square$

                                        =$\frac{441}{2}$

                                        =220.5$cm^{2}$

• Hence,the area of triangle is 220.5$cm^{2}$.
