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

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
