What theorem will you use to find the diagonal of a 10 cm by 8 cm rectangle?

Correct answer: All you need to do is use the pythagorean theorem: where a and b are the sides of the rectangle and c is the length of the diagonal.

What is the length of a rectangle with perimeter?

How can you find the length of a rectangle with the given width and perimeter? Perimeter of Rectangle = 2 (Length + Width) Rearranging the terms in this formula, we get, 1/2 x (Perimeter) – Width = Length So, to find the length of a rectangle, subtract the width from half of the perimeter.

How long is the hypotenuse of right triangle with legs of lengths 3 m and 4 m?

So, the hypotenuse is 5 .

What will be the length of the diagonal of rectangle of side 6m and 8m?

Answer: The diagonal of the given rectangle is 10 m.

How long is the diagonal of a 9 in by 40 in rectangle?

Summary: For the rectangle having a width of 9 units and a length of 40 units, the length of the diagonal is 41 units.

How do you find the breadth of a rectangle if perimeter is given?

If the perimeter and the length of a rectangle are known, the width can be calculated using the formula: Width = P/2 – l, where l = length of the rectangle; and w = width of the rectangle, and P = perimeter of the rectangle.

How do you find the length of the rectangle when the perimeter and breadth is given?

In the same way, if the perimeter and the width are known, the length can be calculated using the formula: Length(L) = P/2 – w. Where P = perimeter of the rectangle; and w = width of the rectangle.

How long is hypotenuse of a right triangle?

In geometry, a hypotenuse is the longest side of a right-angled triangle, the side opposite the right angle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides.
