Question

Find the area of the triangle whose sides are 20 cm, 24 cm and 25 cm ​

Answer 1

Step-by-step explanation:

here,

A=20cm

B=24cm

C=25cm

then,

S=(A+B+C)/2

S=(20+24+25)/2

S=69/2

S=34.5

now by applying herons formula:-

area = √S(S-a)(S-B)(S-C)

after putting the values of S,A,B and C

you will be able to find the area
