Question

find the area of a triangle having petimeter 32cm. one side of its side is equal to 11cm and difference of the other two is 5cm​

Answer 1

Answer:

the answer is 880cm do it in metre square

Answer 2

Answer: Perimeter of a triangle = sum of all side

Let x and x+5 be the other two sides

By question

Perimeter = 11+x+(x+5)

32=11+x+x+5

32-11=2x+5

21-5=2x

16=2x

16/2=x

x=8

then,

x+5=8+5=13

Now, Area of triangle=2 (l+ b)=2x(13+8)

=2x21=42cm sq.
