Which paper has a larger perimeter?

to compare both, you have to have them in the same units

1 inch = 25.4 mm

8.5 inches = 8.5 x 25.4 = 215.9 mm

11 inches = 11 x 25.4 = 279.4

perimeter of US/Canadian A4 = 2(279.4mm+215.9mm)=990.6

perimeter of rest of world A4= 2(210mm+297mm)=1014 (larger)

Area of US/Canadian A4= 279.4mm*215.9mm= 60322.46 mm^2

Area of of rest of world A4= 210mm x 297mm= 62370 mm^2(larger)

is there a picture

step-by-step explanation:

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
