a certain city block is in the form off parallelogram. two of it's side are each 225 meters long, the other two sides are each 145 meters long. if the distance between the first two pair is 80 meters. find the area of the land in the block and the length of the diagonals.

2 answers

the area, of course, is base * height = 225*80 = 18000m^2

Use the law of cosines for the diagonals. The angles between the sides are θ and π-θ, where

sinθ = 80/145
a certain city block is in the form of parallelogram .Two of.its parallel sides are each 130 meters long ;the other two sides are each 70 meters in length .if the distance between the first two parallel sides is 40 meters,find the area of a lot and the length of the diagonals
