The formula for the volume of a cylinder ( V<span>=πr2</span>h) is useable to find the missing height. Then, to find the radius, use the equation, <span>r = square root of (V / (pi x h)). Plug your numbers into the equation and solve.</span>

Gables property Corp is leasing office buildings with an area of 49x^2 + 70x +25
Hoochie [10]

Answer:

Given: Gables property Corp is leasing office buildings with an area of 49x^2 + 70x+25

⇒ Area = 49x^2 + 70x+25

we can write this as:

Area = (7x)^2+2\cdot (7x) \cdot (5) + (5)^2            .....[1]

Use the  identity formula:

(a+b)^2 = a^2+2ab +b^2

then, by using this formula in [1] we have;

Area = (7x+5)^2

or

Area = (7x+5)(7x+5) square units

Area of building = l \times w where l is the length and w is the width respectively;

⇒ l = w = 7x+5 units

Therefore, the possible length and width of the building is;

l = 7x+5 units

w = 7x+5 units

As we know that the Area of a square is equal to side times side . Since each side of a square is the same, it can simply be the length of one side squared.

Therefore, the possible shape of the building is Square.
