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, $A = \frac{bh}{2}$ .....................................(1)

Where, b - Base of triangle

h - Height of triangle

From given value,

b - 8 inches

h - 9

Equation (1) becomes,

$A = \frac{(8)(9)}{2}$
