Question

ABC DEF area of ABC = 64 cm and area of DEF =121cm if EF 15•4cm find BC

Answer 1

Answer:

Step-by-step explanation:

TRIANGLE ABC/TRIANGLE DEF=BC square/ EF square

therefore,

64/121=BC/square of 15.4

taking square root on both the sides

8/11=BC/15.4

thus,

BC=8*15.4/11

BC=11.2 units
