The area of a square garden is 98 m2. How long is the diagonal?

The diagonal is about 14 m

Step-by-step explanation:

A = s^2

98 = s^2

so

s = √98

diagonal c^2 = 98 + 98

c^2 = 196

c = √196

c ≈ 14

Answer:

The diagonal is about 14 m

C = 14

Step-by-step explanation:

The side is the square root of the area

S * S = A

S = √98

The diagonal is the hypotenuse of a right triangle formed by the two sides so

a² + b² = c²

Where C = the diagonal A = √98, B = √98

so C² = (√98) ² + (√98) ²

This gives: C² = 98 + 98 or

C² = 196

√C² = √196

C = 14
