Dana made 96 strides.
Step-by-step explanation:
Given,
Ratio of Sally's stride to Dana's strides = 5:4
Strides made by Sally = 120
Let,
x be the strides made by Dana.
Ratio of Sally to Dana = 120:x
Using proportion;
Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana
Product of mean = Product of extreme
Dividing both sides by 5
Dana made 96 strides.

Step-by-step explanation:
Answer:
139.5 mm
Step-by-step explanation:
The area of a geometric shape with all sides of equal length is:
A (1/2)nsr
n = the number of sides
s = the length of the sides
r = the length of the apothem
The apothem is the line going from the center point of the shape to the middle of one of the sides.
A = (1/2)(5)(9)(6.2)
A = (1/2)279
A = 139.5 mm
The area for a rectangle is length × width.
The area for a parallelogram is base × height.
The area for a trapezoid is height (base 1 + base 2) ÷ 2. The area for a rhombus is base × height.
Hope this helps^^ :)
