Question

if triangle abc is similar to triangle pqr, then find area of triangle ABC: area of triangle PQR. AB =1.4cm,PQ=1.8cm​

Answer 1

Answer:

area of triangle ABC : area of triangle PQR = 49:81

Step-by-step explanation:

since triangle abc is similar to triangle pqr,

then $\frac{area of ABC}{area of PQR}$ = $(\frac{1.4}{1.8})^{2}$= $\frac{49}{81}$    [ formula $\frac{A1 }{A2 }$ = ${(\frac{L1}{L2})^{2} }$ ]
