perimeter of given right triangle
units
perimeter of dilated right triangle
units
area of given right triangle
units²
area of dilated right triangle
units²

Explanation:

Step1: Perimeter of given triangle

Sum the three sides: \(8 + 15 + 17\)
\(8+15 = 23\), \(23 + 17 = 40\)

Step2: Area of given triangle

Use right triangle area formula \(\frac{1}{2} \times \text{base} \times \text{height}\). Base = 15, height = 8.
\(\frac{1}{2} \times 15 \times 8 = \frac{120}{2} = 60\)

Step3: Perimeter of dilated triangle

Dilation scale factor 5, perimeter scales by 5. Given perimeter 40, so \(40 \times 5 = 200\)

Step4: Area of dilated triangle

Area scales by \(5^2 = 25\). Given area 60, so \(60 \times 25 = 1500\)

Answer:

Perimeter of given right triangle: \(40\) units
Perimeter of dilated right triangle: \(200\) units
Area of given right triangle: \(60\) units²
Area of dilated right triangle: \(1500\) units²
