Question

1. In two similar triangles, find the ratio of:

b. the perimeter, if the areas are 50cm and 16cm.​

Answer 1

54cm and 36cm

Explanation:

triangle a : triangle b

50cm² : 16cm²

25 : 8

thus,

area of triangle a :

2cm×25cm

=50cm²

area of triangle b :

2cm×16cm

=32cm²

then,

perimeter of triangle a:

2cm+2cm+25cm+25cm

=54cm

perimeter of triangle b:

2cm+2cm+16cm+16cm

=36cm
