Hello!
<h3><em><u>Answer</u></em></h3>The area of the right triangle is 30 . The perimeter is 40 in.
<h3><em><u>Explanation</u></em></h3>
First, we must find the measure of the hypotenuse of the triangle by using the Pythagorean Theorem.
+
64 + 225 =
√289 =
17 =
Now that we have all the side lengths, we can use the formulas to find the area and perimeter.
<h3>AREA:</h3>A =
A = (15 × 8) ÷ 2
A = 30
<h3>PERIMETER:</h3>P = a + b + c
P = 8 + 15 + 17
P = 40
Answer:
135 units²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
To calculate h use Pythagoras' identity on the right triangle on the left
h² + 8² = 17²
h² + 64 = 289 ( subtract 64 from both sides )
h² = 225 ( take the square root of both sides )
h = = 15 , thus
A = 9 × 15 = 135 units²
