Question

two Sides of a triangle measure m2 + 2mn and 3/4m2 - 2mn. It's perimeter is 9mn. ​

Answer 1

Answer:

Perimeter of a triangle is a+b+c (side+base+side)

Here, Perimeter is 9m

2

−2n+8

and two sides are 4m

2

+3n , 7m

2

+5n−12

Let other side be x

Therefore,

perimeter=a+b+c

=>9m

2

−2n+8=4m

2

+3n+7m

2

+5n−12+x

=9m

2

−2n+8−4m

2

−3n−7m

2

−5n+12=x

=−2m

2

−10n+20=x

Therefore,

the other side is −2m

2

−10n+20
