Question

the height of equilateral triangle is 7√3 . find its perimeter
​

Answer 1

Answer:

as we know that the area of triangle is a1/2 ×base ×height

and the question is that its an equivalent triangle so if its height is 7√3 then it's all sides including base will be 7√3

thus, 1/2×7√3×7√3

hence (7√3)×(7√3 ) = 49×3 = 147

hence 1/2×147 = 73.5 ans

hence 73.5 m/cm ^2 Is your ans
