The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.

A=1/2(9)(4)

Multiply to get 18 square cm, which is choice D.

Easiest question I have ever seen! :)
We know the formula of the area of a triangle
= $(1)/(2)$ ×base×height
The height given is 4 cm (we should take the perpendicular height)
And the base length is 8 cm
Simply, we just substitute the given numbers
= $(1)/(2)$ ×8×4
=18 cm²
The answer is D: 18 square m

Explain why 1/6 is greater than 1/8 but less than 1/3

Answers

You can read fractions as one number divided by another. So 1/6 is equivalent to 1 divided by 6. It is then selfevident that the larger the denominator the smaller the number. If you have one cake and divide it between 3, 6 or eight people, three people will get a larger slice than 6 people sharing the same cake. And 6 people will get a larger slice than 8 people dividing the same cake.

1/6 is greaterthan 1/8 because 4/24 is greaterthan 3/24.

1/6 is lessthan 1/3 because 6/18 is greaterthan 3/18.

We have,

Comparing 1/6 and 1/8:

The denominators are 6 and 8.

A commondenominator for 6 and 8 is 24.

We can convert both fractions to have a denominator of 24:

1/6 = (1/6) * (4/4) = 4/24

1/8 = (1/8) * (3/3) = 3/24

Since 4/24 is greaterthan 3/24, we can conclude that 1/6 is greaterthan 1/8.

Comparing 1/6 and 1/3:

The denominators are 6 and 3 is 18.
