For this problem you will need to know the formula of at least two shapes the square and the triangle can you state them as the following???

the rectangles base is 15 and the triangles in 3 by dividing it.

No, I mean what is the FORMULA for calculating the area of these two shapes?

You certainly can do it Hiy's way but there is an easier way.

This shape is what you in America call a Trapezoid

(we have a different name for it in Australia but I will not confuse you with that)

The area of a trapezoid =  $$\frac{1}{2}* (sum \;of \;parallel\;sides\:)* perpendicular\;height$$

How long are the parallel sides?

What is the perpendicular height?

What is the area of this trapezoid?

The paralle sides = 7 inches

The perpendicular height = I am alittle confused with perpendicular height I dont know which one that is that is a reason I am sruggling with this.

Ok those P words - how confusing!

Parallel and Perpendicular.

Parallel  Lines

what do you see in the middle    ll

they look like railway tracks to me.

They are both going in the same direction!

Parallel lines are like train tracks just like the ll in the middle of the word shows you !

Parallel lines

---------------------------------------------------------------------------------------------------------------------------------------

Perpendicular lines are the other ones. They are at right angles to each other.

Perpendicular lines

Okay and another way to say Perpendicular lines are lines that intercept

Well I see the triangle has a Perpendicular lines  Because tHAT little triangle has a right angle

Yes but perpendicular lines have to intersect at right angles!   That is 90 degrees

Well on the triangle the bottom and the back of the triangle is a Perpendicular line

Ok Nicolas, try again,

How long are the parallel lines and what is the perpendicular height?

Then

What is the area?

Well arent the parallel sides = 7 inches??\

Just to know

No the parallel sides are the top and the bottom, They are running the same direction as each other.

So then if the Parrel lines are bottom and top then the top would be 14in and the bottom would be 15in and the Perpendicular line would be the back of the triangle and the bottom and that is in totall 10in so I am going to add them all up 14+15+10= 39in

I am so sorry I have to go now but we could save this and I can work with you tommorow night since your night is my morning.

No, the parallel lines are  14 and 18   (the top and the bottom)

the perpendicular height is  7

Thats what I said you posted to fast

Xd I feel proud of my self

My way does the whole thing all at once Nickolas. You do not need to worry about seperating the triangle an anything like that.

Melody  Mar 20, 2019

But the bottom parrel line is 18 you got that point.
