Absolute value is always positive, it is the distance from 0
Use the distance formula to find width and length D= sqrt[(<span>x2</span>−<span>x1</span><span>)^2</span>+(<span>y2</span>−<span>y1</span><span>)^<span>2], then use the perimeter formula, P=2width+2length</span></span>
Answer:

Step-by-step explanation:
Answer:
The base is 10 meters
Step-by-step explanation:
The area of a right triangle is (b × h) ÷ 2 = a
Let's input the given values and find the value of b:
(b × 4) ÷ 2 = 20
4b ÷ 2 = 20
2b = 20
b = 10
Check:
(10 × 4) ÷ 2 = 20
40 ÷ 2 = 20
20 = 20
It works!
4(p + r ) - 2p =
4p + 4r - 2p =
2p + 4r <===
