For the area of the deck to be doubled, he should increase each dimension by 3.
<h3>How to find the dimension increase to double the area?</h3>
The deck is 4 feet by 21 feet.
She wants to increase each dimension by equal lengths so that its area is doubled.
Therefore,
initial area = 4 × 21 = 84 ft²
Hence,
The increase by equal length
width = x + 4
length = x + 21
area = 2(84) = 168 ft²
Therefore,
(x + 4)(x + 21) = 168
x² + 21x + 4x + 84 = 168
x² + 25x + 84 = 168
x² + 25x + 84 - 168 = 0
x² + 25x - 84 = 0
(x + 28) • (x - 3) = 0
x = -28 or 3
It can only be positive.
Therefore, she should increase each dimension by 3.

Answer:
answers are given below
Step-by-step explanation:
1.
Circumference = 
Where 2r = Diameter
Hence
Circumference =
2.
No there is no such circle in which relationship between Radius and Diameter can be represented without
.
This is because while deriving the relation the angle measurement ts taken into consideration and the angle are measured in radians i.e. in terms of
not degrees.
3. We can not determine the exact circumference because
is a rational number and but its value is approximately taken from
and
is an irrational number

Step-by-step explanation:
80x+90x=1740,5x+x=6x,
80(6)+90x=1740,1740-480=990,
90x=990,x=11
