Question

Kierra draws a triangle with a base of 10 cm and a height of 15 cm. She dilates the triangle using a scale factor of  45
 . Then, Kierra finds the difference between the two areas by subtracting. How much greater is the area of the original triangle than the area of the dilated triangle?

GPT-5 mini · Answer

I assume the scale factor is 4/5.

Original area = 1/2 · 10 · 15 = 75 cm².  
Area scale factor = (4/5)² = 16/25.  
Dilated area = 75 · 16/25 = 48 cm².

Difference = 75 − 48 = 27 cm².
