Question

7. The areas of two similar triangles are in the ratio 25: 100. If one of the corresponding
sides is 8cm, then the length of the other side is,​

Answer 1

let two similar triangle be ABC and triangle DEF and one of the corresponding be L(AB)= 8cm

ABC SIMILAR DEF

area(ABC)/area( DEF )= L(AB)/L(DE)

25/100=8/L(DE)

4×8=L(DE)

THEREFORE LINE DE IS 32CM
