The area of triangle DEF is 2137.5 cm²
Solution:
Given data:
Area of ABC = 38 cm²
Scale factor = 7.5
To find the area of DEF:
<em>Area of dilated image = Area of original image × (scale factor)²</em>
Area of DEF = 38 × (7.5)²
= 2137.5 cm²
Area of DEF = 2137.5 cm²
The area of triangle DEF is 2137.5 cm²
