What is the surface areaof this square-basedpyramid in square yards?

Given:
There is a square based pyramid given with measurments
Required:
We want to find the area of given pyramid
Explanation:
First we find the area of base which is square
[tex]A_1=5*5=25\text{ sq ft}[/tex]Now the area of sides of pyramid which is triangle
[tex]A_2=4*\frac{1}{2}*8*5=80\text{ sq ft}[/tex]Now the area of pyramid is
[tex]A=25+80=105\text{ sq ft}[/tex]now convert 105 sq ft to sq yard is
1 sq yd is 9 sq ft by this
[tex]A=\frac{105}{9}=11.67\text{ sq yd}[/tex]Final answer:
11.67 sq yard
