The dimensions she would take are length = 24cm and width = 7cm
<h3>What is a rectangle?</h3>
A rectangle is a polygon with 4 sides and 4 right angles.
Analysis:
let the width be = x
Length = 2x + 10
Diagonal = 25
The diagonal, length and width of the rectangle form a right angle triangle and by Pythagoras,
= +
625 = + 4 + 40x + 100
5 + 40x +100 - 625 = 0
5 + 40x - 525 = 0
divide through by 5
+ 8x - 105 = 0
+15x - 7x - 105
x(x + 15) -7(x + 15) = 0
(x-7)(x+15) = 0
since dimension cannot be negative x = 7
so width is 7cm
Length = 2x+ 10 = 2(7) + 10 = 24cm
In conclusion, the dimensions are 24cm and 7cm.

Answer:
2.1 , 2.103 , 2.13 , 2.1312
Step-by-step explanation:
Look at the first place, and see if it's the same, if it is, then you move to the next place. If the place is empty, fill it with a 0 and go from there.
Answer:
2.166666666666667
Step-by-step explanation:
0 + 1 + 1 + 3 + 4 + 4 = 13
13 divided by 6 = 2.166666666666667
Do you know the Combination Formula? If Not it is (n!)/r!(n - r)!
I think n would equal 6, and r would equal 2. So it would be 6!/2!(4!)
I believe you can do this yourself now that I've given you an equation.
