Question

3. If the perimeter of a certain rectangle is 76
and its area 360, then what is the length of
its shortest side?​

Answer 1

Answer:

Okay So the question goes like this

2(l+b)=76

l+b=38

b=38-l   ---- (1)

Substitute this in Area formula.

l*b=360

(38-l)*l=360

l^2-38l+360=0

Apple the quadratic formula

and the

l=20,18

So the shorter side is either 18 or 20.

I think I forgot how to do this but I tried my best.
