Billboard

Rectangular billboard is 2.5 m long with a diagonal 2.8 m long. Calculate the perimeter and the content area of the billboard.

Correct answer:

o =  7.5219 m
S =  3.1524 m2

Step-by-step explanation:

a=2.5 u=2.8 b=u2a2=2.822.521.261 o=2 (a+b)=2 (2.5+1.261)=7.5219 m
S=a b=2.5 1.261=3.1524 m2
