A square of any number is expressed as **n2** where n is a natural number

a) 9^{2} = 9 x 9 = 81

b) 14^{2} = 14 x 14 = 196

c) 0.05^{2} = 0.05 x 0.05 = 0.0025

A square root is the opposite of squares: in the examples aboveb) 14

c) 0.05

a) √81 = 9

b) √196 = 14

c) √0.0025 = 0.05

Can you solve the following question?b) √196 = 14

c) √0.0025 = 0.05

A rectangular plot measuring 54m by 24m has the same area as a square plot. What is the perimeter of the square plot?

**Solution**

Area of the Rectangular Plot:

54 x 24 = 1296m^{2}

A square has 4 equal sides hence its area is L X L = L^{2}

∴ L^{2} = 1296

L = √1296

L = 36m

Perimeter = L + L + L + L = 4L

= 4 x 36

= 144m

Area of the Rectangular Plot:

54 x 24 = 1296m

A square has 4 equal sides hence its area is L X L = L

∴ L

L = √1296

L = 36m

Perimeter = L + L + L + L = 4L

= 4 x 36

= 144m
