The areas of two similar triangles ΔABC and ΔPQR are 25 cm2 and 49 cm2 respectively and QR = 9.8 cm. Then BC = ?


Given :


Area of ΔABC = 25 cm2


Area of ΔPQR = 49 cm2


Length of QR = 9.8 cm.


Since both the triangles are similar so according to the Area –Length relations of similar triangle we can write






The length Of The side BC is 7 cm.
