How many times should he go around to mow one half of the lawn?

Randy and his sister agreed that they would each mow one-half of the lawn. The lawnis 25′ x 45′ rectangle. The lawn mower cuts a path two feet wide. Randy starts at one corner and mows a path completely around the outside.

Lawn is 25′ by 45′ = 1125′

First time around he mows 1125′ – (21*41) = 1125-861 = 264′

Second time he mows 861′ – (17*37) = 232′

Third time he mows 629 – (13*33) = 200′

Half of 1125 is 562.5.

He needs to mow 264 + 232 + 200x = 562.5

496 + 200x = 562.5

66.5 = 200x

x = .3325

He needs to mow all the way around twice and about 1/3 the way around the third time.
