=============================

a) Given Area: 18 cm² and base: 9 cm

$\sf \rightarrow (1)/(2) (9)(h) = 18$

$\sf \rightarrow h = (18(2) )/(9)$

$\sf \rightarrow h = 4$

∴ The height of the triangle is 4 cm

b) Given Area: 32 m² and height : 4 m

$\sf \rightarrow (1)/(2) (b)(4) = 32$

$\sf \rightarrow b = (32(2))/(4)$

$\sf \rightarrow b = 16$

∴ The base of the triangle is 16 m

c) Given Area: 480 mm² and base: 30 mm

$\sf \rightarrow (1)/(2) (30)(h) = 480$

$\sf \rightarrow h= (480(2))/(30)$

$\sf \rightarrow h=32$

∴ The height of the triangle is 32 mm
