Answer:
Step-by-step explanation:
I think it would be 12. just use the Pythagorean theorem
5^2+b^2=13^2
25+b^2=169 Now we subtract 25 on both sides
b^2=144 now we do the square root of 169
B=12
The perimeter of a rectangle is 2 times the length and 2 times the width. Since you got the perimeter (240), you can multiply 2 by the length (160) and subtract the perimeter (240) by it, giving you 80. This is 2 times the width. Divide that by 2 (divide 80 by 2) and you will get 40. The width is 40 feet.
Volume of a Triangle= (b•h•l)/2
(13•10•4)/2
(520)/2
260
V=260
Answer:
Its 40 for the first and 20for the other one
