Circumference 6598

Adam had three identical rectangles. He put them together and got a rectangle with a circumference of 50 cm. Then, he placed them differently and got a rectangle with a larger circumference. Calculate its perimeter.

Correct answer:

o2 =  70 cm

Step-by-step explanation:

o1=50 cm  a=2b o1=3a+4b a=2b 50=3a+4b  a=2 b 50=3 a+4 b  a2b=0 3a+4b=50  Pivot:Row1Row2 3a+4b=50 a2b=0  Row231 Row1Row2 3a+4b=50 3.33b=16.67  b=3.3333333316.66666667=5 a=3504b=3504 5=10  a=10 b=5  o2=2 b+6 a=2 5+6 10=70 cm
