it would depend how much you actually used, but you would take the amount you used  and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

Amira is painting a rectangular banner 2 1/4 yards wide in the cafeteria. The banner will have a blue background. Amira has enou
Dominik [7]

we know that

the area of the rectangular banner is equal to

A=W*h

where

W is the wide of the banner

h is the height of the banner

in this problem

W=2\frac{1}{4} \ yards=\frac{(4*2+1)}{4} =\frac{9}{4} \ yards

A=1\frac{1}{2} \ yards^{2} =\frac{(1*2+1)}{2} =\frac{3}{2} \ yards^{2}

In the formula of the area solve for h

A=W*h\\ \\ h=\frac{A}{W}

Substitute the values of W and A

h=\frac{\frac{3}{2}}{\frac{9}{4}}  \\ \\ h=\frac{2}{3} \ yards

therefore

the answer is

the height of the banner is \frac{2}{3} \ yards
