The area of the given parallelogram is 120.
Step-by-step explanation:
Step 1:
The parameters needed to determine the area of a parallelogram are the base length and height.
The base length of this parallelogram is 15 inches while its height is 8 inches.
The area of a rectangle is determined by multiplying the base length with the height.
Step 2:
The area of the parallelogram
Here the base length is 15 inches and the height is 8 inches.
The area of the parallelogram
So the area of the given parallelogram is 120.
Answer:
The ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
Step-by-step explanation:
Let the Area of smaller watch face be
Also Let the Area of Larger watch face be
Also Let the radius of smaller watch face be
Also Let the radius of Larger watch face be
Now given:
We need to find the ratio of the radius of the smaller watch face to the radius of the larger watch face.
Solution:
Since the watch face is in circular form.
Then we can say that;
Area of the circle is equal 'π' times square of the radius 'r'.
framing in equation form we get;
So we get;
Substituting the value we get;
Now 'π' from numerator and denominator gets cancelled.
Now Taking square roots on both side we get;
Hence the ratio of the radius of the smaller watch face to the radius of the larger watch face is 4:5.
