Answer :
so 20=72%
percent means parts out of 100
72%=72/100
20=72/100 of area of square
area of square =x
20=72/100 times x
solve for x
multiply both sides by 100/72 to clear fraction
27 and 7/9=x
the area=27 and 7/9 square cm or cm^2
percent means parts out of 100
72%=72/100
20=72/100 of area of square
area of square =x
20=72/100 times x
solve for x
multiply both sides by 100/72 to clear fraction
27 and 7/9=x
the area=27 and 7/9 square cm or cm^2
ratio and proportion
20 cm/72%= x cm / 100%
cross multiply
72 x= 20000
x= 27.78
A= 27.78 cm^2
hope this helps
