Well, you can do your own homework, but here is the general outline of what you must do. Use the variable "x" to express the width of the rectangle. In that case, because of the ratio, the length will be (4/3)x. Write an equation for the area of the rectangle, replace x, (4/3)x and the known area, and solve for "x". (Since a quadratic equation will give you two solutions, you will obviously accept the positive solution.) Once you calculate "x", you can easily calculate the other side of the rectangle, as (4/3)x. Finally, use the Pythagorean Theorem to calculate the diagonal.
Another Answer:-
1 Let the dimensions be 3x and 4x
2 So 3x*4x = 369.63 or 12x2 = 369.63
3 Divide each side by 12 and then square root each side
4 Therefore: x = 5.55 and dimensions must be 16.65 by 22.2
5 Using Pythagoras: 16.652+22.22 = 756.9025 and its square root is 27.75
6 Answer: length of diagonal = 27.75 cm
Using Pythagoras' theorem the length of the diagonal is 20 feet
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
If you know its dimensions then use Pythagoras' theorem to find the length of its diagonals.
Anything you want, so long as (Length in inches)2 + (Width in inches)2 = 1,764
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
Using Pythagoras' theorem the length of the diagonal is 20 feet
If they are the dimensions of a rectangle then use Pythagoras' theorem to find the length of the diagonal.
You use the pythagorous theorm to calculate the hypotenuse of the triangle, which is the same line as the diagonal. 7(7)+ 10(10)= diagonal x diagonal 149= diagonal x diagonal Diagonal= square root of 149: this approximates to 12.207in Visit quickanswerz.com for more math help/tutoring! Consider a rectangle with dimensions 7 inches by 10 inches. Let ABCD be the rectangle. We need to find the length of the diagonal. We know that the diagonals of a rectangle are same in length. So, it is enough to find the length of the diagonal BD. From the rectangle ABCD, it is clear that the triangle BCD is a right angled triangle. So, we can find the length of the diagonal using the Pythagorean Theorem. BD2 = BC2 + DC2 BD2 = 102 + 72 BD2 = 100 + 49 BD2 = 149 BD = √149 BD = 12.207 So, the length of the diagonal is 12.21 inches.

If you know its dimensions then use Pythagoras' theorem to find the length of its diagonals.
The diagonal is 7.21 feet.
Anything you want, so long as (Length in inches)2 + (Width in inches)2 = 1,764
To find the length of a diagonal in a rectangle, use the Pythagorean method. Diagonal length = square root(length squared + height squared).
The length of the diagonal is about 16.03 feet.
Using Pythagoras, the diagonal is sqrt(122 + 162) = sqrt(144 +256) = sqrt(400) = 20 feet.
-- A rectangle has no 'formula'. -- The length of the diagonal is 24feet 10.62inches (rounded)
The diagonal is 26cm
The diagonal length is about 18.44 inches.
