Question

The perimeters of two similar triangles ABC and PQR are respectively 40 cm and 60 cm. If PQ = 12 cm then find
ar(PQR)/ar (ABC)
02:3
03:7
09:4
04:9​

Answer 1

PQ = 12

then

Ab= 12

therefore they are similar

then all sides are 12

given

perimeter is 40 and 60

area of pqr = 1/ 2 ( a + b )

= 1/2( 12+12)

=1/2× 24

= 12

so,

Answer 2

Answer:

(D)4:9 I think this is right answer
