Question

Plz give me the answer of 14th with steps and correct answer

Answer 1

Step-by-step explanation:

it is a equilateral triangle so it will be equal

1st side is 2x+ 3

so 2nd and 3rd will be equal that is 2x+ 3

so s1 +s2+ s3 =240

or 2x +3 +2x +3 +2x +3= 240

or 2x+ 2x+ 2x +3+ 3+ 3= 240

or 6x +9 =240

or 6x= 240 -9

or 6x =231

or x= 231 /6

or x= 38.5
