If the areas of two similar triangles ABC and PQR are in the ratio 9 : 16 and BC = 4.5 cm, what is the length of QR?
Given: ΔABC and ΔPQR are similar triangles. Area of ΔABC: Area of ΔPQR = 9:16 and BC = 4.5cm.
To find: Length of QR
We know that the ratio of the areas of two similar triangles is equal to the ratio of the squares of any two corresponding sides.
`QR= 6 cm`
