The area of the triangular sign is 36 square inches, if Gabrielle is cutting a triangular sign with a base of 8 inches and the perpendicular distance from the base of the sign to its vertex is 9 inches.
Step-by-step explanation:
The given is,
Gabrielle is cutting a triangular sign
Base of 8 inches
The perpendicular distance from the base of the sign to its vertex is 9 inches
Step:1
Formula for area of triangle is,
Area, [tex]A = \frac{bh}{2}[/tex].....................................(1)
Where, b - Base of triangle
h - Height of triangle
From given value,
b - 8 inches
h - 9
Equation (1) becomes,
[tex]A = \frac{(8)(9)}{2}[/tex]
[tex]=\frac{72}{2}[/tex]
= 36
Area of triangle sign, A = 36 square inches
Result:
The area of the triangular sign is 36 square inches, if Gabrielle is cutting a triangular sign with a base of 8 inches and the perpendicular distance from the base of the sign to its vertex is 9 inches.
