Question

maths answer please....proper answer or i will report ​

Answer 1

Step-by-step explanation:

2(l+b)= 120

l+b =60

b=60-l

and

lb= 675

l(60-l)=675

60l-l^2=675

l^2-60l+675=0

l^2-45l-15l+675=0

l(l-45)-15(l-45)=0

(l-45)(l-15)=0

l=45

l=15

if l=45 ,then b=60-45=15

if l=15,then b=45

so length and breadth are 45 and 15
