What is the surface area of a square property possessing sides measuring 15 m?

Select your answer for: What is the surface area of a square property possessing sides measuring 15 m?
Show answer

Answer: A. 225 sq m

Explanation

The geometric formula for the area of a square is the side length squared. Multiplying fifteen meters by fifteen meters results in an area of two hundred twenty five. The resulting square meters correctly reflect the two dimensional property measurements provided. A square is a regular quadrilateral possessing four equal sides and four right angles. Surface area represents the total two dimensional space enclosed within the boundary of a figure. Squaring a linear dimension converts it into standard units of square measure.

Real estate professionals calculate square footage to determine property values and pricing. Landscaping projects require accurate area measurements to purchase appropriate amounts of sod. Flooring installations rely on square area calculations to minimize material waste during cutting. Option B is a slightly incorrect estimation that does not match the exact squaring calculation. Option C represents an incorrect calculation derived from a ten by ten meter property. Option D incorrectly adds the side lengths together instead of squaring the dimension.

Q6. Two inlet spigots fill a basin in 10 minutes and 15 minutes individually, and when combined with an open drain pipe, the basin fills in 18 minutes. How long does the drain pipe take to empty the completely filled basin?

Select your answer for: Two inlet spigots fill a basin in 10 minutes and 15 minutes individually, and when combined with an open drain pipe, the basin fills in 18 minutes. How long does the drain pipe take to empty the completely filled basin?
Show answer

Answer: D. 9 min

The combined flow rate of the two inlet pipes is found by summing their individual rates. Subtracting the net combined filling rate of eighteen minutes from the inlet rate gives the drain rate. Inverting the resulting dr...
