Question 362015
Draw the figure in a coordinate plane and find its area.
Rectangle defined by L(–2, –4), M(–2, 1), N(7, 1), and P(7, –4)
Choose one answer.
	a. 36 sq units 	
	b. 40 sq units 	
	c. 45 sq units  	

	
to draw: the points go clockwise from L, L is in lower left corner, line segments LM & PN are the width, MN and LP are the length,
LM = PN = width, MN = LP = length
use distance formula to find width and length
D = sqrt((x2 - x1)^2 + (y2 - y1)^2)
LM = sqrt((-2 + 2)^2 + (1 + 4)^2)
LM = sqrt(5^2)
LM = sqrt(25)
LM = 5
MN = sqrt((7 + 2)^2 + (1 - 1)^2)
MN = sqrt(9^2)
MN = sqrt(81)
MN = 9
area = width * length = LM * MN = 5 * 9 = 45
answer is c. 45 sq units
