A pennant is a shape of a triangle has a base of 12 inches and a height of 30 inches. What the area of the pennant?

180 square inches

Step-by-step explanation:

Area, A is given by A=0.5bh where b is base and h is height. Since both of these dimensions are provided then we substitute the given figures into the formula. Substituting 12 inches for base, b and 30 inches for height, h then the area will be equivalent to

A=0.5*12*30=180 square inches.

Therefore, the area of the described triangle is 180 square inches.
