pasagot ulit,ung tamang sagot, with solution,salamat​


Sagot :

Answer:

38/2=19, half of the perimeter

84=2*2*3*7=(2*2*3)*7=12*7

the length and width are 12m and 7m

if you want quadratic equations...

P=2l+2w

38=2l+2w

19=l+w

l=19-w

A=lw

84=(19-w)w

84=-w^2+19w

w^2-19w+84=0

factor

84=2*2*3*7=12*7

(w-12)(w-7)=0

w-12=0

w=12

w-7=0

w=7

not sure hehe but goodnight ily>33
