Please help, I've been trying to figure this out for an hour.

8

Step-by-step explanation:

hypotenuse is always double the short leg there for your answer would be 8 because 16/2 = 8

8

Step-by-step explanation:

Well this is a right triangle which means that you can use the Pythagorean Theorem to solve it.

a^2+b^2=c^2

The 2 lines on the other 2 sides means that those 2 sides are congruent so they are the same

C is the hypotenuse and a=b so

a squared + a squared = 16 squared = 156

that should help you get started

49,000

Step-by-step explanation:

To get the area of the dilated rectangle, we need the dilated dimensions

We simply multiply the scale factor by the dimensions

we have this as;

3.5 * 50 = 175 cm

and

3.5 * 80 = 280 cm

The area of the dilated rectangle is thus;

280 * 175 = 49,000 cm^2
