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 * side \: length`

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

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

`\qquad \sf  \dashrightarrow \:a = 60 / 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)`
