Question

After Clara ran 8 times around a square field, she covered a distance of 288 km. Calculate the area of the field in metres.

Answer 1

Answer:

8.1 ×10⁷ m² is the ANSWER

Step-by-step explanation:

Let the length of the square field be x km

therefore, perimeter of the square field =4x km

As Clara ran 8 times around a square field, she covered a distance of 288 km.

so, 8×4x = 288

or, 32x = 288

or x = 288÷32

=》x = 9

therefore, the length of the square field is 9km

hence the length of the square field in metres is 9000 m

Now, the area of the square field in metres

=》(length)²

=》(9000)² m²

=》81000000 m²

=》8.1 ×10⁷ m²
