Question

If ∆ABC ~ ∆PQR, A (∆ABC) = 80, A (∆PQR) = 125, then fill in the blanks​

Answer 1

hello friend

i don't know maa

Answer 2

Answer:

Given

ΔABC∼ΔPQR

A(ΔABC)=80

A(ΔPQR)=125

According to theorem of areas of similar triangles ""When two triangles are similar, the ratio of areas of those triangles is equal to the ratio of the square of their corresponding sides'

∴

A(ΔPQR)

A(ΔABC)

=

PQ

Therefore,

A(ΔPQR)

A(ΔABC)

=
