124 + 124 + 64 + 64 =376
376/4=94
Good ol' Joe will need 94 bushes.

there are two ways to do this,
this is a perrimiter problem.
length of perimiter = P
P= 2(l +W)
=2(64+124)
=(2 * 64) + (2 * 124 )
= 128 + 248
= 366 feet ( the perrimiter of the lawn)
to space them 4 feet apart
366 / 4= 90
answer is 90 bushes

If the parameter of his lawn is 64 ft wide on one side, it will be 64 ft wide on the other, and if it is 124 ft long on one side, it will be 124 ft long on the other side.
So 64 ft + 64 ft + 124 ft + 124 ft
= 376 ft
that is the number of feet total for the entire parameter
If each bush is planted 4 feet apart, divide the number of feet by 4
376 ft / 4 ft = 94
He will need 94 bushes.

94
perimeter=all 4 sides or
(64+64+124+124)=376
then he plants one every 4 feet so you divide by 4
376/4=94

2(64/4)+2(124/4)
32+62

others answered 94 but four corner of the lawn have common bushes so 4 of them must be decreased from that no. so the answer is

Havent been in math in a while....but I got 94
124/4= 31
64/4=16
31*2= 62
16*2=32
62+32=94
If you get stuck on problems like these...draw a box and try to actually visualize the problem...maybe youre a visual learner like me :)
