Arectangle is 13 centimeters wide and 18 centimeters long. how long is it’s diagonal

The length of the diagonal  = 22.20 cm

Step-by-step explanation:

Here, the length of the rectangle = 18 cm

Also, the width of the rectangle = 13 cm

Let us assume the diagonal of the rectangle = k cm

As we know, EACH INTERIOR ANGLE OF THE RECTANGLE = 90°

So, if we join the opposite vertices of the rectangle, a Right angled triangle is formed.

Here, the length of the Rectangle  = Perpendicular of the right Δ

Width of the Rectangle  = Base of the right Δ

Diagonal of the Rectangle  = Hypotenuse of the right Δ

Now, by PYTHAGORAS THEOREM:

or,

or, Diagonal = 22.20 cm

Hence, the length of the diagonal  = 22.20 cm

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

answer: x=60
