7 fill in the blank 1 point
find the area of the triangle with the measurements given below.
base = 6 in
height = 4 in

type your answer...

Explanation:

Calculate the perimeter of the triangle in Question 5

$$ P = 3.5\text{ in} + 5\text{ in} + 5.5\text{ in} = 14\text{ in} $$

Calculate the area of the parallelogram in Question 6

$$ A = \text{base} \times \text{height} = 9\text{ cm} \times 5\text{ cm} = 45\text{ cm}^2 $$

Calculate the area of the triangle in Question 7

$$ A = \frac{1}{2} \times \text{base} \times \text{height} = \frac{1}{2} \times 6\text{ in} \times 4\text{ in} = 12\text{ in}^2 $$
