In order for Mateen to walk a kilometer(1000m) in his rectangular backyard, he must walk the length 25 times or walk its perimeter 10 times. What is the area of Mateen's backyard in square meters

400

Step-by-step explanation:

25 times the length is 1000 m.

Let length = L

25L = 1000

L = 40

10 times the perimeter is 1000 m.

Let the perimeter = P

10P = 1000

P = 100

perimeter = 2L + 2W

2(40) + 2W = 100

80 + 2W = 100

2W = 20

W = 10

The length is 40 m, and the width is 10 m.

A = LW

A = 40 m * 10 m

A = 400 m^2

i would go with the first one

step-by-step explanation:

hope this

the answer would be 1 1/72

step-by-step explanation:

you can rewrite the equation by separating the parts and then solving individually:

10-9=1

1/8 - 1/9=

find l c d and then combine:

1 1/72
