Work out the height of this triangle with base, b = 8mm and
area, A = 218.8mm?,

54.7 mm

Step-by-step explanation:

use the formula area= 1/2 base time height

A=1/2bh

54.7mm

Step-by-step explanation:

Area=1/2b×h

218.8=0.5×8×h

218.8=4h

h=218.8÷4

h=54.7

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

i would need to see the dot plot : )
