Question

perimeter of two similar triangles ABC and PQR are 60 and 36 respectively if PQ is 9 then find AB

Answer 1

so ratios of corresponding sides of two triangles are equal to ratio of their perimeters.
.
hence perimeter of ABC/ perimeter of PQR = AB/ PQ
.
60/36= AB/9.
.
AB = 60× 9/36.
.
AB =15cm
