The area of parallelogram is 640 sq cm . Find the height and the base if its base is four times its corresponding height
Answers
Given:
The base of a parallelogram is 4 time of its corresponding height.
Area of the parallelogram is 640 sq cm.
Find:
Base and the corresponding height of the parallelogram
Solution:
Let the base of Parallelogram be 'b' cm
Let the height of Parallelogram be 'h' cm
The base of a parallelogram is 4 time of its corresponding height.
=> b = 4h .......(1).
We know that,
The area of parallelogram = base × height
=> 640 = base × height
=> 640 = 4h × h (From equation .1)
=> 640 = 4h²
=> 640/4 = h²
=> 160 = h²
=> √160 = h
=> 12.64 = h
=> h = 12.64cm
Putting the value of 'h' in equation 1.
=> b = 4h
=> b = 4 × 12.64
=> b = 50.56cm
Hence, the base of the Parallelogram is 50.56 cm and height of the Parallelogram is 12.64cm.
I hope it will help you.

Answer:
Let the present age of Aaron be 'x' years.
Let the present age of Ron be 'y' years
Aaron is 5 years younger than Ron
=> x = y + 5 .......(i).
4 years later Aaron will be twice as old as Ron
Aaron's age = (x+ 4) years
Ron's age = (y+4) years
=> (x + 4) = 2(y + 4
