Area and perimeter of rectangle

The rectangle area is 3000 cm2, and one dimension is 10 cm larger than the other. Determine the perimeter of the rectangle.

Final Answer:

o =  220 cm

Step-by-step explanation:

3000 = ab a = b+10  3000=b (b+10)  3000=b (b+10) b210b+3000=0 b2+10b3000=0  p=1;q=10;r=3000 D=q24pr=10241(3000)=12100 D>0  b1,2=2pq±D=210±12100 b1,2=210±110 b1,2=5±55 b1=50 b2=60  b=b1=50 cm a=b+10=50+10=60 cm  o=2 (a+b)=2 (60+50)=220 cm
