Question

sovle this question guys !

Answer 1

let first side=3x
let second side=3x
let third side=2x
perimeter=sum of all sides
32=3x+2x+3x
32=8x
32/8=x
4=X
X=4
first side =3×4=12cm
second side=3×4=12cm
third side =2×4=8cm


by heron formula
area of triangle=

Answer 2

perimeter of an triangle is equal to the sum of all the threes sides

here the three sides are in ratio 3:3:2(there are two three as the 2 sides of the isosceles triangles are equal)

the perimeter is 32

then let the angles be 3x 3x and 2x

then atp the equation will be

3x +3x+2x=32
8x=32
x=4

therefore the angles are 3*4=12
3*4=12
2*4=8

we know that area of triangle is 1/2 *base *height
we know
base is 8
then two sides are 12
so we need to take out the height ( diagram is given in attachment)



$12 {}^{2} = 4 ^ 2 + x {}^{2}$

$144 = 16 + x ^{2}$
x =11.31
then we will add 11.31 once more as we divided it into 2 parts

ie 22.62 now height is 22.62
then area
1/2*base*height
i.e.1/2*8*22.64

ans 90.56
