Question

PLEASE HELP!!

A certain city block is in the form of a parallelogram. Two of its sides measure 32ft. and 41 ft. If the area of the land in the block is 656ft^2, what is the length of its longer diagonal?

Answer 1

Don't know answer, but useful: facts are
area = base x height = bh
sides are a, b
diagonal = sqrt(a^2 + b^2 - 2 ab cos A),
where A is angle opposite the diagonal

Answer 2

thanks man
ive been trying to solve this but still i dont know whats the right and wrong answer

Answer 3

Try breaking it into two triangles, then use law of sines:

a/sinA = b/sinB = c/sinC

where a is side opposite angle A etc.
