Answer:
h = 2.7 m
Step-by-step explanation:
ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal
DE / BC = AD / AB, that is
h / 0.9 = 18 / 6 ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7
so what you would do is 20 x 12 and see what you get and the subtract it from 900 and then see what number would take you to 900
