Question

A rectangle park measures 300 ft by 400 ft. A sidewalk runs diagonally from one corner to the opposite corner. Find the length of the sidewalk.
a.
400 ft
c.
250 ft
b.
500 ft
d.
650 ft

Answer 1

Since the park is rectangular, it has 4 90-degree interior angles. Connecting any corner to the diagonally opposite corner is the same as drawing the HYPOTENUSE of a right triangle inside the park boundaries. Does that help you visualize the layout? Draw a picture and label whatever it is that you know.

Answer 2

from pythagorean theorem

a^2 + b^2= c^2 there is a famous triangle 3-4-5

3^2 + 4^2=5^2
9+16=25

what if i multiply all these values by 100??

Answer 3

zpupster is one up on me. Nice work! Now, Nathan, what next?

Answer 4

I need to find the hypotenuse hold I now how to do that

Answer 5

You're right on target. Please review the Pythagorean Theorem.

Answer 6

Ok so I got 250000 now I need to find the square root of it and I'll have my answer. Ugh big numbers give me headaches

Answer 7

It's b 500! Right?

Answer 8

500*500=250000

Answer 9

yes!!

Answer 10

Alright a! Thank you!

Answer 11

look for the 3-4-5 in a lot prolem or multiples of
6-8-10
9-12-16
12-16-20

etc. etc. etc.
