Question

Question number seventeen​

Answer 1

Explanation:

Let x be the third side,

Then (3x−4) will be length of the equal sides.

As per the question-

55=x+2(3x−4)

55=x+6x−8

55=7x−8

55+8=7x

63=7x

9=x

Therefore, the third side = x=9m.

Hence, the equal two sides = (3x−4)=(3×9−4)=27−4=23m each.
