Circumference 4003

Calculate the diagonal length of a rectangle whose length is 3 cm greater than its width and whose circumference is 18 centimeters.

Final Answer:

u =  6.7082 cm

Step-by-step explanation:

a=3+b o=18 cm  o=2a+2b o=2(b+3)+2b o/2 = 3+2b  b=(o/23)/2=(18/23)/2=3 cm a=3+b=3+3=6 cm  u=a2+b2=62+32=3 56.7082 cm   Verifying Solution:  o2=2 a+2 b=2 6+2 3=18 cm
