You can put this solution on YOUR website!
area of a triangle is: A=b%2Ah%2F2


if given: b=+2ft and A=+28ft%5E2}
A=b%2Ah%2F2....plug in given values
28ft%5E2=%282ft%2Ah%29%2F2
28ft%5E2=%28cross%282%29ft%2Ah%29%2Fcross%282%29
28ft%5E2=1ft%2Ah
28ft%5E2%2F1ft=h
28ft%5Ecross%282%29%2F1cross%28ft%29=h
highlight%2828ft=h%29

if given: h=22.6yd and A=+282.5yd%5E2
A=b%2Ah%2F2....plug in given values
282.5yd%5E2=%28b%2A22.6yd%29%2F2
282.5yd%5E2=%28b%2Across%2822.6%2911.3yd%29%2Fcross%282%29
282.5yd%5E2=b%2A11.3yd
282.5yd%5E2%2F11.3yd=b
