Answer 2

Step-by-step explanation:

Given :-

• Equilateral triangle of side 24cm

• L = 24 cm

To Find. :-

• find the length of altitude?

Solution :-

We have ,

Area =√3/4×l ^2

putting all values :-

= √3/4×24 ×24

= √3×6×24

= 144√3 cm^2

Now ,

Area = 1/2×l ×h

putting values :-

=> 144√3 = 1/2×24×h

=> 144√3 =12h

H =144√3/12

h =12√3

the length of altitude is 12√3.
