Option D:
[tex]x=5\ .\ (\frac{1}{2}\times 14\times6)[/tex]
Solution:
Base of the triangle = 14 inch
Height of the triangle = 6 inch
Area of the triangle = [tex]\frac{1}{2}\times bh[/tex]
where b is base and h is height.
Substitute the given values in the formula.
Area of the triangle = [tex]\frac{1}{2}\times 14\times6[/tex]
Area of the 5 triangles = [tex]5\ .\ (\frac{1}{2}\times 14\times6)[/tex]
Let total amount of plywood be taken as x.
Total amount of plywood = Area of the 5 triangles.
[tex]\Rightarrow x=5\ .\ (\frac{1}{2}\times 14\times6)[/tex]
Option D is the correct answer.
[tex]x=5\ .\ (\frac{1}{2}\times 14\times6)[/tex]
Hence this equation can be use to solve for the total amount of plywood.
