The surface area of the given figure would be
A=103.11.

Considering the given figure is a square pyramid, the formula for finding surface area would be
A=a^2+2a\sqrt{(a^2)/(4)+h^2 }.


A=a^2+2a\sqrt{(a^2)/(4)+h^2 }


5^2+2*5*\sqrt{(5^2)/(4)+7.4^2 }
103.1089=103.10Our Final Solution

Hope this helps!
