Answer:
41 units
Step-by-step explanation:
In this question, you should remember that the diagonal drawn will represent the longest side of the triangle that will be formed .This is to say the triangle will have the two shorter sides (the length and width) and the longest side (diagonal).
Apply the Pythagorean relationship where
The formula to apply here will be
Diagonal = 41 units
It is given that,a rectangle has a width of 9 units and a length of 40 units.
<u>To find the diagonal of rectangle</u>
We know that rectangle can be considered as combination of two right triangles.
Here length of right triangle = 40 units and height = 9 units
Hypotenuse = diagonal of rectangle.
Hypotenuse² = Length² + height
= 40² + 9²
= 1600 + 81
= 1681
Hypotenuse = √1681 = 41
Therefore diagonal of rectangle = 41 units
