Step-by-step explanation:

Given

The attached triangle

Required

Number of square feet materials needed

This simply means that we calculate area;

$Area = 0.5 * base * height$

$Area = 0.5 * (14ft\ 2in) * (8ft\ 6in)$

Convert to ft [divide by 12]

$Area = 0.5 * (14+ 2/12) * (8+ 6/12)$

$Area = 0.5 * (14.17) * (8.5)$

$Area = 60.23ft^2$

(B) is correct
