Question

Can anyone explain this to me??

Answer 1

Try multiplying 17 x 12.75 and see what answer that gives you. I'll be glad to help with questions you have on this.

Answer 2

You have to use the Pythagorean Theorem
a^2+b^2=c^2

You use this to find the hypotenuse

We know one side of the rectangle is 17 and the other is 12.75, so they will be a and b

The sum of the squared a and b is 451.5625

We square that if we want to find c

Hypotenuse (c) = 21.25
