Question

triangle ABC similar to triangle PQR if area of abc=81cm^2 and area of PQR=169cm^2 and AC=7.2cm find the length of pr?

Answer 1

since triABC~triPQR we get, AB/PQ=BC/QR=AC/PR------equation1 so now, arABC/arPQR=CA/RP (from eq1) 81/169=7.2/RP 81RP=169*7.2 RP=169*7.2/81 RP=1216.8/81 RP=15.02cm (round off 15.02cm to the nearest if you prefer whole number) hope this helped you Anna!

Answer 2

I hope you understand
