Problem: the area of a garden is 48 m2 , what is the greatest perimater the garden could have?
please help im stuck im in grade 5
The counter-question has to be, how unreasonable do you want to be?
Here are several pairs of numbers that give the designated area:
W,L 2W 2L P A
6,8 12 + 16 = 28 6*8 = 48
4,12 8 + 24 = 32 4*12 = 48
3,16 6 + 32 = 38 3*16 = 48
2,24 4 + 48 = 52 2*24 = 48
1,48 2 + 96 = 98 1*48 = 48
As you can see, shortening the width increases the
perimeter, but makes the garden ridiculously narrow.
