Question

A square has an area of 285.61m2.
Work out the perimeter of the square.

Answer 1

Given,

Area of the given square is 285.61 square metre.

Solution,

for calculating the perimeter of the square we have to calculate the length of one side of the given square.

Let,the length of the one side of the square is = x metre ( x = variable)

So,the area of the square = x² m²

Now, comparing the value of area that we have calculated and the value of the area given in the question,we get the following mathematical equation.

x² = 285.61

x = 16.8

So,the length of the square = 16.8 metre

The perimeter of the square = (16.8×4) = 67.2 metre

Hence,the perimeter of the given square is 67.2 metres.
