Wreck Site PlotVertexPArcheologists are studying a shipwreck onthe ocean floor. The wreck site is roughlyshaped like a parallelogram. Thearcheologists make a map of the site in thecoordinate plane.Each unit on the map represents 1 m.According to the map, what is the area ofthe wreck site?Location(9,2)(-8,2)(-7,7)Not yet mapped, but tothe right of point RRs-10Math Toolkit graph paper, rulersPer Deckractive

Answer 1

First, we need to map the coordinates as:

Where the points P, Q, R, and S are equal to (9,2), (-8,2), (-7,7), and (10, 7) respectively.

Then, the area of the parallelogram can be calculated as base times height. So it is equal to:

Base = 9 - (-8) = 9 + 8 = 17

Height = 7 - 2 = 5

Area = Base*Height = 17*5 = 85

Answer:

$\text{Area = 85m}^2$
