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.

Result

o =  7.522 m
S =  3.152 m2

Solution:

a=2.5 u=2.8 b=u2−a2=2.82−2.52≐1.261 o=2⋅ (a+b)=2⋅ (2.5+1.261)≐7.5219≐7.522 ma=2.5 \ \\ u=2.8 \ \\ b=\sqrt{ u^2-a^2 }=\sqrt{ 2.8^2-2.5^2 } \doteq 1.261 \ \\ o=2 \cdot \ (a+b)=2 \cdot \ (2.5+1.261) \doteq 7.5219 \doteq 7.522 \ \text{m}
S=a⋅ b=2.5⋅ 1.261≐3.1524≐3.152 m2S=a \cdot \ b=2.5 \cdot \ 1.261 \doteq 3.1524 \doteq 3.152 \ \text{m}^2
