Question

The diagonal of a square is 15 m; find the length of its one side and perimeter.​

Answer 1

Answer:

length of one side = 10.6m and perimeter = 42.4 m

Step-by-step explanation:

diagonal of square = 15m

let side of square be = a

a^2 + a^2 = (15)^2 = 225

a^2 = 225/ 2 = 112.50

a = √112.50 = 10.6 m

perimeter = 4 * a

= 4*10.6

= 42.4

Ans) length of one side is 10.6m and perimeter is 42.4m
