Answer:
24.8 [tex]inches^{2}[/tex]
Step-by-step explanation:
Height of a triangular shaped piece of wood bought by Sue =12.4 inches
Height of a triangular shaped piece of wood= 4 inches
Area of fabric required to cover the triangle = Are of a triangle
As we know the area of triangle= [tex]\frac{1}{2}[/tex] × base ×height
So, Area of a triangle= [tex]\frac{1}{2}[/tex] × 12.4 ×4
So, Area of a triangle= 12.4×2
Area of a triangle= 24.8 [tex]inches^{2}[/tex]
Amount of fabric required to cover area of a triangle is 24.8 [tex]inches^{2}[/tex]
Hence the correct answer is 24.8 [tex]inches^{2}[/tex]
