Three triangles are shown on the centimetre grid. A
B
C
(a I already did)
b)
Work out the area of this triangle.
Give your answer as a decimal.

C has the largest area. It is 4.5 square units.

Step-by-step explanation:

A:

area = bh/2 = 2 * 3/2 = 3

B:

area = bh/2 = 2 * 3/2 = 3

C:

area = bh/2 = 3 * 3/2 = 4.5

C has the largest area. It is 4.5 square units.

d? maybe

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
