Answer:
Answer is 27, 32, 45
Step-by-step explanation:
In the right angle triangle, hypontenous is the longest side.
∴ In each option square of longest side has to be equal to the sum of square of other two side.
We know, ( as per pythogorean theorem)
If we check the last option; 27, 32, 45
In the given set of integer, we have longest side as 45
∴ conisdering 45 as hyptenous
Subtituting the value in the formula
⇒
⇒
⇒
∴
Hence, the set of given integer is not a pythagorean triple and are not side length of right angle.
First, let's divide the figure in two parts, called "A" and "B (View the figure attached):
a: The paralelogram
b: The rectangle
To find the area of the parallelogram, we must apply the following formula:
A=bxh
b: is the base of the parallelogram.
h: the height of the parallogram.
We can know the length of the base and the heigh by the figure shown in the problem:
b=4
h=3
Then, we have:
A(a)=bxh
A(a)=4x3
A(a)=12
Now, we must proceed to find the area of the rectangle, by using the formula:
A(b)=bxh
b=9 (the base of the rectangle)
h=3 (the height of the rectangle)
A(b)=9x3
A(b)=27
Then, the area of the figure is:
At=A(a)+A(b)
At=12+27
At=39
