Question

*8. A rectangular piece of paper is folded along the dotted line to form
Figure A.
Find the perimeter and area of the piece of paper.
figure A of folded paper has width 21 cm and length 29 cm​

Answer 1

Step-by-step explanation:

p. of rectangle = 2 (l+b)

= 2 (29+21)

= 2×50

= 100

Answer 2

the perimeter of the folded piece of paper is 71 cm, and the area of the folded piece of paper is $304.5 cm^2$.

Assuming that the paper is folded in half along the dotted line, the folded piece of paper will have dimensions of 14.5 cm by 21 cm.

To find the perimeter of the folded piece of paper, we need to add up the lengths of all four sides. The two shorter sides each measure 14.5 cm, and the two longer sides each measure 21 cm. Therefore, the perimeter of the folded piece of paper is:

Perimeter =$2(14.5 cm) + 2(21 cm) = 29 cm + 42 cm = 71 cm$

To find the area of the folded piece of paper, we simply multiply the length by the width:

Area = length x width =$14.5 cm \times 21 cm = 304.5 cm^2$

Therefore, the perimeter of the folded piece of paper is 71 cm, and the area of the folded piece of paper is $304.5 cm^2$.
