Answer 1

(b) 60.21ft^2

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
