Question

A triangle has a base of 9 feet and a height of 12 feet. What is the area of the triangle? 42 ft2 54 ft2 84 ft2 108 ft2 PLZ HELP ASAP

Answer 1

the area of the triangle
9×12÷2=54ft

Answer 2

Area of the triangle = 54 ft²

Explanation:

To find the area of the triangle with a base of 9 feet and a height of 12 feet, we will simply use the formula;

Area of triangle =
`(1)/(2)` × b × h

where b = base of the triangle

h=height

From the question given, base=9 feet and height=12 feet

We can now proceed to insert the values into the formula;

Area of triangle =
`(1)/(2)` × b × h

=
`(1)/(2)` × 9 × 12

(At the right-hand side of the equation,2 at the denominator will divide 12 to give 6) Hence;

= 9 × 6

=54

Area of the triangle = 54 ft²
