First , divide the figure into 2 rectangles like this:

Got it so far?

Yeah so first I divide it and time 60 x 20?

Nope. divide it, you'll get this:

So I would do 60 - 20?

Now, calculate the area for the rectangle and the square :|
Can you do it?

How do the shaded part first. How do you calculate the area for that?

Would you cut it in to pieces?

I don't want to cut it anymore, Cutting once is enough for this question :/

Hmm ok after cutting it onces would that make half of ten 5?

Should i demonstrate how to do it?

You're sorry but you laugh... interesting :\
Now consider the shaded area, you can apply the formula
Area = width x length , Since it is a rectangle.
So Area of the shaded part, let's call it A1, = (60-20) x 10 = 40 x10 = ...
Understand?

Yes so that would be the formula and what I would do?
Callisto

That's the formula for calculating area of rectangle. you need to calculate area of the A1 and A2, then add them up. That'd be the area you want for answer

Would 400m be the answer?
Callisto
Best Response

1
Nope, 400 is only for A2 /A1 lol
You need to add A1 and A2 together :)

So would I add 400M +400M = 800M??

Yes!!! but the unit is not M it's m^2

Sorry...
First cut it into 2 as you did.

Can you find x and y?

Would I add both numbers to find the x and y?

x =1 since it is a rectangle, that's the property of it.
y = 7-1 =6

Now, calculate the area of 2 rectangles.
|dw:1336007524975:dw|
A1 = 1 x 6
A2 = 6 x 4
like the previous one, do addition for the 2
