Hello, you need to Add all the perimeters together and if asking for one find the length of it but if wanted total add;)
We know that
[the area of the root]=4*[area of one lateral triangle side]
area of one lateral triangle side=b*h/2
b=10 ft
h=9.4 ft
area of one lateral triangle side=10*9.4/2-----> 47 ft²
[the area of the root]=4*[47]-------> 188 ft²
the answer is
the area of the root is 188 ft²
