Relatively 81129

The sides of the rectangle are relatively 5:4, and the perimeter of the rectangle is 308 dm. Find the area of the rectangle.

Correct answer:

S =  5855.8 dm2

Step-by-step explanation:

a:b=5:4 o=308 dm  o=2(a+b) = 2(5 x + 4 x)  x=2 5+2 4o=2 5+2 4308=915417.1111 dm  a=5 x=5 17.1111=977085.5556 dm b=4 x=4 17.1111=961668.4444 dm  S=a b=85.5556 68.44445855.8025 dm2   Verifying Solution:   o2=2 (a+b)=2 (85.5556+68.4444)=308 dm r2=a:b=85.5556:68.4444=45=1.25=5:4
