The sides of two similar triangles are in the ratio 2 : 3, then the areas of these triangles are in the ratio ______________ Given that Ratio of sides of similar triangles = 2/3 We know that If two triangle are similar , ratio of areas is equal to the ratio of squares of corresponding sides . Therefore, (π΄π‘Ÿπ‘’π‘Ž π‘œπ‘“ π‘‘π‘Ÿπ‘–π‘Žπ‘›π‘”π‘™π‘’ 1)/(π΄π‘Ÿπ‘’π‘Ž π‘œπ‘“ π‘‘π‘Ÿπ‘–π‘Žπ‘›π‘”π‘™π‘’ 2)=(𝑆𝑖𝑑𝑒 π‘œπ‘“ π‘‘π‘Ÿπ‘–π‘Žπ‘›π‘”π‘™π‘’ 1)^2/(𝑆𝑖𝑑𝑒 π‘œπ‘“ π‘‘π‘Ÿπ‘–π‘Žπ‘›π‘”π‘™π‘’ 2)2 = (2/3)^2 = πŸ’/πŸ— So, the required ratio is 4 : 9
