Question

In triangle ABC,BC=4cm,AD=7cm and BE=5cm . find the length of AC​

Answer 1

SOLUTION-:

GIVEN

BC = 4 CM

AD = 7CM

BE = 5CM

FIND

Length of AC

let's begin

`(1)/(2) * side \: * height \: \\ (1)/(2) * ac * bd = (1)/(2) bc * ad \\ (1)/(2 ) * 5 = (1)/(2) * 4 * 7 \\ ac = (4 * 7)/(5) \\ \\ = (28)/(5) \\ = 5.6cm \\ \\ so \: we \: required \: \\ length \: of \: ac = 5.6 \\ therefore \: we \: get \: answer`
