The length of the rectangle is in the ratio of 5:12, and the circumference is 238 cm. Calculate the length of the diagonal and the area of the rectangle.

Correct answer:

u =  91 cm
S =  2940 cm2

Step-by-step explanation:

o=238 cm s=o/2=238/2=119 cm s=a+b  a=s 5+125=119 5+125=35 cm b=s 5+1212=119 5+1212=84 cm  u=a2+b2=352+842=91 cm
S=a b=35 84=2940 cm2
