Question

Find the area
and perimeter of a
Square
plot of land, the length of whose diagonal is
15 metres. Give your answer correct to a
place of decimals.​

Answer 1

Answer:

Let the side of the square be x

Thus, 15 *2=x*2+x*2

⇒225=2x *2

⇒x *2=112.5

⇒x=10.61

Thus, area of the square =112.5 sq. m

Perimeter =4x

=4×10.61

=42.43 m
