hardy flare
#

honest rock
#

hm

hardy flare
honest rock
#

4cm is the sides of white area if theres ^ arrows

#

just nvm

#

im trying to figure out smthng

hardy flare
#

we must identify height and base and seperate accordingly and use them in formula relating to the shapes

honest rock
#

alright

hardy flare
#

so trapezium formula = 1/2(a + b)(height)

honest rock
#

what is the height?

hardy flare
#

therefore

#

16

#

?

#

18*

storm goblet
#

have you subtracted

hardy flare
#

ok perimeter = 37.5cm² and white region area = 18cm²

honest rock
storm goblet
hardy flare
#

?

#

uhh

storm goblet
#

it's the area of the outer trapezium

hardy flare
#

so what is it

#

Ohh

honest rock
#

what about brown area?

hardy flare
#

alright

storm goblet
#

but continue please

hardy flare
#

ok so 37.5cm² - 18cm² = 19.5cm²

#

let me check

#

YEAHHH ITS RIGHT

honest rock
#

hm

hardy flare
#

ok is this the end or do we want more questions

honest rock
#

how u find 37.5?

#

where does it come from

hardy flare
honest rock
#

i dont get it

hardy flare
#

imagine it as a whole trapezium

#

the white region and brown

honest rock
#

never heard of this trapezium

hardy flare
#

and the height of the trapezium is 5cm, top = 9cm and bottom 6cm

#

Additionally

#

The sum of the parallel sides in trapezium means the top and bottom

honest rock
#

5x9 45-6 1/2= 37.5?

storm goblet
hardy flare
#

so 9cm + 6cm

honest rock
#

ignore it

#

i think its prq
Step Q is the final step

#

idrk

hardy flare
#

Thanks for your perspective

valid cove
#

actually its rpq nvm

# hardy flare so tuff, help please find the colored region area?

$$\text{Area of a trapezium} = \frac{1}{2}(a + b)(h)$$
where $a$ and $b$ are the two sides parallel to each other, and $h$ is the perpedicular height between them.

This can be shown by considering that the area of a trapezium is the combined area of two triangles inside the trapezium.
