c^2 = a^2 + b^2
c^2 = 16^2 + 20^2
c^2 = 256 + 400
c^2 = 756
Now, square root both sides.
<h2><em><u>
c = 27.5 in</u></em></h2>
10+10=20 = length
20 + 18 = 38 width = 18 or 9 on each side
10 x 9 = 90
Answer 90
Answer:14
Step-by-step explanation:
x+y=56
x:y=5:3
Sum of ratio=5+3
Sum of ratio=8
x=5/8x56
x=(5x56) ➗ 8
x=280 ➗ 8
x=35
y=3/8x56
y=(3x56) ➗ 8
y=168 ➗ 8
y=21
x-y
35-21=14
x-y=14
