Ответ:
Kevin need 14.14 feet of red tape
Step-by-step explanation:
Given: (Figure Attached)
Area of Square = 25 square feet
As we know
Area of square = length x width = a x a = 25
a * a = 25
a = ±5 by taking square root both sides
It means a = 5 as the length can not be negative
Now we know the length of sides of square and as shown in figure we can break the figure in two triangles,
By using Pythagoras theorem on one triangle we will find the length of one line of x and then multiply the x with 2 to get the overall feet of tape.
x = ± 7.07 It means x = 7.07
Now the total tape required is 2 * x = 2*7.07 = 14.14
