Question

The area of a triangular mat is 18m2 and the length of one sides, b=3. Find the height

Answer 1

Base of triangle = 3 m

Area = 18 m^2

=> Base *Height / 2 = 18

=> Base *Height = 36

=> 3*Height = 36

=> Height = 12 m

Answer 2

hii!!

here's ur answer...

given base is 3m.

area of the triangular mat = 18m²

therefore 1/2×b×h = 18m²

=> 1/2×3×h = 18m²

=> 1.5×h = 18m²

=> h = 18/1.5

=> h = 12m

verification:-

area of the triangular mat = 1/2×b×h

= 1/2×3×12

= 3×6

= 18m²

hence verified

thus the altitude of the triangular mat is 12m

hope this helps..!
