Answer:

h = 6 cm

Explanation:

Atriangle = b×h/2

18cm² = 6cm×h/2

36cm² = 6cm×h

h = 36cm²/6cm

h = 6 cm

Answer:

Base = 6 cm

Explanation:

Area of Triangle =
(1)/(2) .{base}.{Height}

Where A = 18 cm², h = 6 cm

Putting in the above formula

18 =
(1)/(2)(base)(6)

18 = 3(base)

base = 18/3

Base = 6 cm
