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 $\frac{2}{3} \ yards$
