<h2>
Area of rectangle is 10L-L²</h2>
Step-by-step explanation:
Let L be the length and W be the width.
Perimeter of rectangle = 2 ( L + W )
That is
2 ( L + W ) = 20
L + W = 10
W = 10 - L
We need to express the area of the rectangle as a function of the length of one of its sides.
Area = Length x Width
A = LW
A = L(10 - L) = 10L-L²
Area of rectangle is 10L-L²
Answer:
8
Step-by-step explanation:
The answer is A (6 √2) Because your formula ends up being 7^2 + x^2 = 11^2
7^2 + x^2 = 11^2
Becomes
49 + x = 121
So subtract 49 on both sides to get x by itself
x = 72
And Find the square root of x
72 = 6 √2
