Question

4. The formula for finding the area A of a triangle is
given by A = zbh, where b and h represent the base
and the height of the triangle respectively.
(i) If b = 20 cm and h = 45 cm, find the area of
the triangle.
(ii) If A = 30 cm² and b = 10 cm, find the height of
the triangle.​

Answer 1

Answer:

450

6

Step-by-step explanation:

use the formula a=1/2(b*h)

Answer 2

area = bh/2

i) 20*45/2 = 450cm²

ii) 30 = 10h/2

30*2 = 10h

60 = 10h

h = 60/10 = 6
