What are the five characteristics of edge cities?

1.The area should have at least 5 Million square feet of leasable office space.
2.The area should have more jobs than homes.
3.The area must have 600,000 of leasable retail space.
4.The population perceives it as one place.(The area should have it i.e entertainment, recreation, shopping)
5.The area was nothing like a city 30 years

The area should have at least 5 Million square feet of leasable office space.2. The area should have more jobs than homes.3. The area must have 600,000 of leasable retail space.4. The population perceives it as one place.(The area should have it i.e entertainment, recreation, shopping)5. The applanation was nothing like a city 30 yearsExplanation:
An edge town is associate American term for an amount of business, shopping, and recreation outside a standard downtown (or central business district) in what had antecedently been a residential or geographical region.
The area should have quite 5 million sq. feet of 
office area (about the area of a good-sized downtown)
2. The place should embrace over 600,000 sq. feet of retail area (the size of an oversized regional looking mall)
3. The population should rise each morning and drop each afternoon (their area unit a lot of jobs than homes)
4. The place is understood as one finish destination (entertainment, shopping, recreation, etc.)
5. the realm should not are something sort of a "city" thirty years past (for example cow pastures).

81 is a composite number

In a right-angled triangle: 1- the hypotenuse is the longest side2- we can apply pythagorean rule which states that: (hypotenuse)^2 = (side1)^2 + (side2)^2for the given triangle,longest side is 15 cm  side1 = 9 cmside2 is 12 cm  to check whether the triangle is right-angled or not,compare (15)^2 to the summation of (9)^2 and (12)^in other words, compare 225 to the summation of 81 and 144if they are both equal, then the triangle is right-angles, otherwise, it is not.you haven't provided the diagram showing her work, so i cannot tell the choice. however, apply my explanation to the question you have.
