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.
