Answer:

see explanation

Explanation:

Using the given formula for area : A =
(1)/(2) bh

(a) given b = 8 and h = 5, then

A =
(1)/(2) × 8 × 5 =
(1)/(2) × 40 = 20 units²

(b) given A = 18 and b = 4, then

18 =
(1)/(2) × 4 × h = 2h ( divide both sides by 2 )

h = 9 units

(c) given A = 14 and h = 7, then

14 =
(1)/(2) × 7 × b = 3.5b ( divide both sides by 3.5 )

b = 4 units
