What is the square root of 450

or 21.213

Step-by-step explanation:

For radical form: think of multiples of 450. Think of a pair that contains one perfect square, particularly the higher, the better . These 2 numbers are 25 and 18. 25 is the perfect square number since the two numbers that multiply to be 25 is 5 and 5.

Now take the perfect square of 25 and put it outside of the radical. The 18 remains inside:

Now, since 18 is a high number that needs to get reduced, do the same for 18 as we did for 450--find two numbers, one of which is a perfect square. These two numbers are 9 and 2.

Now take the perfect square of 9. This is 3. Take it out of the radical so that only the two remains inside. The 3 will now multiply with the 5:

Multiply 5 and 3 to get 15. The 15 stays outside the radical. Your answer is:

12 in

Step-by-step explanation:

Let

h > the height of the rectangular canvas

we know that

The diagonal represented the hypotenuse of a right triangle and the height represent the opposite side to the angle of 31 degrees

so

sin(31°)=h/23.3

Solve for h

h=(23.3)sin(31°)=12 in
