Question

5. Find in square metres, the area of a square of side 40.5 dam.​

Answer 1

Answer:

164025 m²

Step-by-step explanation:

We have,

Side of the square = 40.5 dam = 40.5 x 10 m = 405 m     [ Since 1 dam = 10 m ]

Area of the square = (Side)² = (405 m)²

                                         = 164025 m²

....

Answer 2

Answer:

$Area= 164025 \ m^2$

Step-by-step explanation:

Given side of square is  $a=40.5$

so side $a=405$ m

Area of square is   $A=a^{2}$

so Area of square is   $A=(405)^2$

$\implies A=164025 \ m^2$
