Which teacher will help me do it, thank you

Let the height of the triangle of 1 be h 2, the height of the triangle of y and the width and length of the rectangle are a b, so there are 6 b*h 2

ab 6=b*y 2 h+y=a so ab=3by=18

This question is a substitution.

Let the length of the rectangle be x and the width of the rectangle y. The height of the triangle is a, and the height of the triangle is the area of the rectangle.

then a+b=x

1/2ax=6

1/2bx=1/6xy

From the above equation, s=18

Suppose the area of the rectangle is x

then 1 6x+6=1 2x

The solution is x=18

That is, the area of the rectangle is 18.

It should not be necessary to prove why the area of circle 1 plus circle 2 is half the size of the rectangle.

The answer is 11 square centimeters. It is calculated according to the formula of the area of the rectangle and the area of the triangle. No. 1 and No. 2 are equal-bottomed triangles. Hinting at this, I'm sure you'll be able to make it soon.

1 3, the two triangle vertices make perpendicular lines to both sides, and you can see it.

The sum of the area of the two triangles of 1,2 is equal to half of the area of the rectangle, and No. 2 accounts for 1 6, then No. 1 accounts for 1 3,6*3=18 square centimeters.

I can't see clearly, I can't see clearly, I can't see clearly.

There is no solution because: odd + odd = even, even + even = even, odd + even = odd.

Can be rolled out of the impossible.

The area of the circle: square centimeters) ==

So the answer is. Please adopt, thank you

First of all, you can practice questions (1) and (2) on your own. It's okay if you don't practice it, anyway, the teacher doesn't look into it.

Then there is the sentence formation question:

Thank you, Mom.

Mom, thank you (it should have been thanks, but there was a mistake on the paper) You brought me to this beautiful world, because with you, I will be a strong child, whenever I am sick, you always stay up late every day to take care of me;

Whenever I'm sad, you always wipe away my tears!

You've done so much for me!

Mom, when I grow up, I will definitely care about you as much as you took care of me when I was a child!

Mom, I love you!
