Question

B) The perimeter of a squared field is 60 m. Find its area.​

Answer 1

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's solve ~

Perimeter of square is :

$\qquad \sf \dashrightarrow \:4 \times side \: length$

so, we can take side length as a, and solve for a ~

$\qquad \sf \dashrightarrow \:4a = 60$

$\qquad \sf \dashrightarrow \:a = 60 \div 4$

$\qquad \sf \dashrightarrow \:a = 15$

Now, since we know the side length. let's find Area of square :

$\qquad \sf \dashrightarrow \: {15}^{2}$

$\qquad \sf \dashrightarrow \:area = 225 \: m {}^{2}$
