Rectangular 5611

The rectangular course is 12 m longer than its width. Suppose its length increases by 10 m and its area increases by 600 square meters. What are its dimensions?

Correct answer:

a =  72 m
b =  60 m

Step-by-step explanation:

a=12+b S=ab ab+600=(a+10) b a(a12)+600=(a+10) (a12)=(72+10) (7212)=120 10a=720 a=720/10=72 m
b=a12=7212=60=60 m S=a b=72 60=4320 m2
