Question
The corresponding medians of two similar triangles are
12 cm and 15 cm. If the area of the first triangle is 288 cm, then find the area of the second triangleSolution
Let the area of the second triangle = x cm² Then (Area of the first triangle ×) (median of the second triangle) ² = (area of the second triangle) × (median of the first triangle) ² 288 × 225 = x × 144 x = 450cm²
