Question

1) The perimeter of a square lawn is 40 m. What is the length of its

sides? What is its area?​

Answer 1

Answer:

perimeter of square is : 4× sides ; 40m

4×s = 40

S= 40/4

S=10 m

Area = side×side

=10×10

=100m

Answer 2

Answer :

Given :

• Perimeter of square lawn = 40 m

• length = ?

• Area = ?

To find area and length of square.

${\underline{\boxed{\bf{Perimeter \: of \: Square \: = 4 \times side}}}}$

• To find Side :

$\implies \sf 40 \: = 4 \times side \\ \\ \sf\implies \: side \: = \frac{40}{4} \\ \\ \bf\implies \: side \: = 10$

So, Side of Square = 10 m.

${\underline{\boxed{\bf{Area \: of \: Square \: = side \times side \: ( {a}^{2} )}}}}$

• To find area :

$\sf\implies \: Area \: = side \times side \\ \\ \sf\implies \: 10 \times 10 \\ \\ \bf\implies \: 100 \:$

So,Area of Square is 100 m².
