Hello,

This question of construction is related to a triangle ABC.

The given perimeter of the triangle ABC is 75 cm,

If the perimeter is 75 cm, then it wouldn't form a triangle since side AC is very large. And if it is 7.5cm instead, even then, sum of two sides, AB and BC, is greater than the perimeter and hence, a triangle cannot be formed.

But if you wish to derive an answer from the given info, then since AB+BC= 10cm and the given perimeter of triangle ABC is = 75cm, side AC will be equal to 75-10 =65 cm.

Please check the values given in the question. You can repost the question with correct values on Careers360 to get the answer.

Hope this helps.
Thanks.
