Answer:
12
Step-by-step explanation:
using pythagoras theorem
here 15 is hypotenuse since it is opposite 0f 90 degree
9 and x are the other smaller sides of a triangle
according to pythagoras thorem the sum of square of two smaller sides of a triangle is equal to the square of hypotenuse. So,
9^2 + x^2 = 15^2
81 + x^2 = 225
x^2 = 225 - 81
x^2 = 144
x =
x = 12
If x = 4 and y = -2, the value of
2
1 xy² is

B. Exactly 1/4
C. Exactly 3/4
D. More than 3/4
The width of the rectangular lot is 33 meters and the length of the rectangular lot is 37 meters.
Let, the width of the rectangular lot is W meters.
According to the problem, the length of the rectangular lot is 4 meters more than the width, so the length would be (W + 4) meters.
Now, we can use the formula for the perimeter of a rectangle:
Perimeter = 2 * Length + 2 * Width
Given that the perimeter is 140 meters, we can set up the equation:
140 = 2 * (W + 4) + 2 * W
Now, solve for W:
140 = 2W + 8 + 2W
Combine like terms:
140 = 4W + 8
Subtract 8 from both sides:
132 = 4W
Finally, divide by 4:
W = 33
So, the width of the rectangular lot is 33 meters.
Now, we can find the length:
Length = Width + 4
Length = 33 + 4
Length = 37
Therefore, the length of the rectangular lot is 37 meters.

the length is 37 and the width is 33 if you add 33+33+37+37 you get 140
