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
#12 is 2,246.4 I think if not sorry
1:14 means that for every 1 cm it is drawn at it is actually 14 cm
so multiply 4 x 14 = 56
it is actually 56 cm wide
