Question

Find the altitude corresponding to side EF, if ar(∆ ABC) = ar(∆ DEF). If AB = 8 cm and altitude corresponding to AB is 5 cm, EF = 10 cm. *​

Answer 1

Answer:

4cm

Step-by-step explanation:

ar of triangle ABC = AR of DEF.

1/2 X AB X ALTITUDE = 1/2x EF X ALTITUDE

1/2 x 8 x 5 = 1/2 x 10 X ALTITUDE

20 cm² = 5cm x altitude

ALTITUDE = 20cm²/ 5cm

ALTITUDE =. 4 cm
