Anna walks around a square park of side 90m. mary walks around a rectangular park of length 80 m and breadth 60 m. each one makes four rounds. who covers less distance and by how much?

Mary covers less distance for  320 m

Step-by-step explanation:

Psqere=4a

Prect=2(a+b)

anna=4*4a (a=90m)

Anna=16*90=1440m

Mary=4*2(a+b)=8(a+b)=8*(80+60)=8*140=1120 m

anna-Mary=1440-1120=320m

Mary covers a lesser distance with 1120m

Step-by-step explanation:

For Anna: perimeter = 4L

L = 90m

Perimeter = 90×4

= 360m

Work for times round, the total distance will be = 4 × 360

= 1440m

For Mary: Perimeter = 2L + 2b

L = 80m, b = 60m

Perimeter = 2(80) + 2(60)

= 160 + 120

= 280m

For four times = 4 × 280

= 1120m

: Mary covers a lesser distance

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

-4

do 6-10=

if u need it to be negative.
