Answer
The distance between to her house and the school is 1.575 miles.
Step by step explanation
Eugene walked all the way to school = 3mph
She ran back at the rate (r) = 7 mph
Let's "d" is distance between her house and the school.
time(t) = distance/rate
Time taken = 45 minutes
d/3 + d/7 = 45/60
Now we have to find the LCD of 3 and 7, that is 21
(7d + 3d)/21 = 45/60
10d/21 = 45/60
Cross multiply and find the value of "d"
10d * 60 = 45*21
600d = 945
d = 945/600
d = 1.575 miles

you’re welcome
Step-by-step explanation:
Area for square= l*w*h
Area for triangle = l*w / 2
230 * 230 = 52,900
187 * 230/2 = 21,505
21,505 * 4 (because there are 4 triangles)= 86,020 m
52,900 + 86,020 = 138,920 m^2
