a
To find : The base length of a rectangle with given area and altitude
a
Answer to Problem 4PSA
The base length is
Explanation of Solution
Given information : The following information has been given
The area of rectangle
The altitude of the rectangle
Formula used : The area of any rectangle will be
Calculation : We know that the area of any rectangle will be
Hence, substituting the values from the given information, we get
Thus, we get
b
To find : The length of the diagonal of a rectangle with given side and area
b
Answer to Problem 4PSA
The diagonal length is
Explanation of Solution
Given information : The following information has been given
The area of rectangle
The altitude of the rectangle
The base length is
Formula used :
Pythagoras theorem
Where
“ a ” is the hypotenuse of the right-
“ b ” is the base of the right-angle triangle
“c” is the perpendicular of the right-angle triangle
Calculation :
We calculate the diagonal of the rectangle from the sides by using Pythagoras theorem
Thus, we get
