Question

length of diagonal square field is 7√2 find perimeter

Answer 1

Answer:

28 units.

Step-by-step explanation:

Consider a Square ABCD, where AD is the diagonal.

Let 'S' be the side of the square.

Given,

AD = 7√2 units

we know that by using Pythagoras theorem,

AD² = AC² + CD²

=> (7√2)² = S² + S²

=> 2S² = 98

=> S² = 49

=> S = 7 units.

Perimeter of Square = 4 * Side = 4 * 7 = 28 units.
