Answer:

Option 1st is correct

area of a triangle is, 80 in²

Explanation:

Area of triangle(A) is given by:

$A = (1)/(2) b \cdot h$

where,

b is the base

h is the height or altitude of the triangle respectively.

As per the statement:

Base of a triangle(b) = 10 inches and

Height = altitude(h) = 16 inches

Substitute these in [1] we get:

$A = (1)/(2)(10) \cdot 16$

⇒
$A = 5 \cdot 16 = 80$ in²

Therefore, the area of a triangle is, 80 in²
