Question

So I understand this question, but I’m having a problem solving it. The question is – -----------------------------------------------------------------



Mrs. Stewart bought a rectangular plot of land. On a map, the coordinates of the vertices are (6, 0), (12, 3), (11, 5), and (5, 2).

Each square unit on the map represents 4 acres. Mrs. Stewart purchased the land for $41,280.

What was the price per acre?
$ _________


-------------------------------------------------------------------- I get the question, and I’m so close to figuring it out. The problem is I’m trying to figure out how many squares are in this rectangle. Do the little triangles on the edges count as a square?

Answer 1

Answer 2

here the length of the base is:
\[d = \sqrt {{{\left( {{x_2} - {x_1}} \right)}^2} + {{\left( {{y_2} - {y_1}} \right)}^2}} = d = \sqrt {{{\left( {12 - 6} \right)}^2} + {{\left( {3 - 0} \right)}^2}} = ...?\]

Answer 3

@Michele_Laino Thank you for the formula, but I kind of just wanted to know how many squares there were...

Answer 4

I know, nevertheless we have to compute the base , and the height of our rectangle

Answer 5

so what is the base of your rectangle?
hint:
\[base = \sqrt {{{\left( {12 - 6} \right)}^2} + {{\left( {3 - 0} \right)}^2}} = \sqrt {36 + 9} = ...?\]
