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

Correct answer:

u =  6.7082 cm

Step-by-step explanation:

a=3+b=3+3=6 o=18 o=2a+2b o=2(b+3)+2b o/2=3+2b b=(o/23)/2=(18/23)/2=3 a=3+b=3+3=6 o2=2 a+2 b=2 6+2 3=18 u=a2+b2=62+32=3 5=6.7082 cm
