Question

The perimeter of a rectangular garden is 322 feet. If the width of the garden is 72 feet, what is its length?

Answer 1

divide 322 by 2 and then subtract the width

322 /2 = 161

161-72 = 89

 length is 89 feet

Answer 2

perimeter of a rectangle = sum of sides

p =  L+L+W+W

P= 2L + 2 W = 2L +(2x72) 

2L +(2x72)  = 322

2L= 322- 144

2L= 178 
L= 178/2= 89 feet
