How to find the area of the figure?
2 answers:
Answer:
You can break the figure up into 3 rectangles which I have colored red, yellow and pink.
The red rectangle will be 5m x 9m
the yellow rectangle will be 4m by (14m - 5m -5m) which equals 4m x 4m
and the pink rectangle is the same as the red rectangle - 5m x 9m
the area of the red rectangle is 5x9 = 45m2
the area of the yellow rectangle is 4x4=16m2
the area of the pink rectangle is 5x9=45m2
the area of the figure is 45+16+15=106m2

Answer:
Leon is correct. (Option 1)
Step-by-step explanation:
Given that Leon verified that the side lengths 21, 28, 35 form a Pythagorean triple using this procedure.
Step 1: Find the greatest common factor of the given lengths: 7
Step 2: Divide the given lengths by the greatest common factor: 3, 4, 5
Step 3: Verify that the lengths found in step 2 form a Pythagorean triple.
we have to explain whether or not Leon is correct.
As, 3,4,5 forms a Pythagorean triplet i.e satisfies the Pythagoras theorem
⇒
Let a, b, c forms a Pythagorean triplet
Multiplied by 4 on both sides
⇒
⇒
Hence, we say 4a, 4b and 4c also forms a Pythagorean triplet.
∴ multiplying every length of a Pythagorean triple by the same whole number results in a Pythagorean triple.
Hence, Leon is correct.
Answer:
A. the difference of two squares
Step-by-step explanation:
we are given
we can write
so, we can see that
x^2 is square
11^2 is also square
so,
It means that
two squares are subtracted
so, it is difference of two squares
so,
A. the difference of two squares
