Circumference 5254

Calculate the shorter side and the diagonal of the rectangle if one side is 2 cm longer than the other and its circumference is equal to 70 centimeters.

Correct answer:

a =  16.5 cm
u =  24.7891 cm

Step-by-step explanation:


b=a+2
2(a+b)=70

b=a+2
2•(a+b)=70

a-b = -2
2a+2b = 70

a = 33/2 = 16.5
b = 37/2 = 18.5

Our linear equations calculator calculates it.
u=a2+b2=16.52+18.52=24.7891 cm
