Arectangular park is 400 m long and 200 m wide. if you walked around the park twice, how far would you walk? awnser : 160,000 -( i need w/ the second pt plsss )
(if you walked diagonally across the park from corner to corner, how far would you walk (round to
the nearest meter)?

calculate the perimeter of the rectangular park do 2{400)+2(200)

then find the answer then times 2 the answer

Step-by-step explanation:

for second one with the diagonal use the Pythagorean theorem do 400sqared + 200squared then square root the answer

~447 meters

Explanation: Since it is a rectangular park, there are 4 right angles. By having a diagonal through the rectangle, we have formed two right triangles. We know the length and width of the park but we need to know the diagonal. We can use the Pythagorean Theorem a^2+b^2=c^2.

By substituting 400 for a and 200 for b (or 200 for a and 400 for b, it doesn’t matter), we get that 160000+40000=c^2 or 200000=c^2. We then take the sqrt of each side to arrive at c=447.2135955... or about 447 meters

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
