Answer:
25 blocks
Step-by-step explanation:
using a coordinate plane, set (0,0) as the mall location. 1 unit will represent 1 block.
(0,0)
east 15 blocks ---> (15,0)
25 blocks north---> (15, 25)
40 blocks west ---> (15-40,25) = (-25,25)
25 blocks east
(-25 + 25,25) = (0,25)
distance formula given by
d = [tex]\sqrt{(x-x_1)^2+(y-y_1)^2}[/tex] given points (x,y) and (x1,y1)
plug and chug
d = 25
