Question

let one of the sides of a triangle be 17 cm and the sum of all the sides of the triangle be 40 cm the sum of two adjacent sides is 35 cm, then the area of the triangle is​

Answer 1

Answer:

1800 cm square

Step-by-step explanation:

let sides be x,y,z

let x be 17 as per the question

and

x+y+z=40

now x+y=35

therefore y =35-17=18

which leaves us with z which is equal to 5

now using the area formula [s(s-x)(s-y)(s-z)]

we get

1800 cm square
