The area of a square garden is 98m squared. How long is the diagonal?

diagonal is 14 m

Step-by-step explanation:

We are given;

The area of a square garden as 98 m²

We are required to determine the diagonal of the square.

We know that;

Area of a square = s², where s is the side of the square

Therefore;

s² = 98

Thus;

s = √98

To get the diagonal

s² + s² = diagonal squared

Hence;

Diagonal squared = (√98) ² + (√98) ²

= 98 + 98

= 196

Thus;

Diagonal = √196

= 14 m

Thus, the diagonal is 14 m
