Question

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

Answer 1

Answer:

Diagonal of square = 15

a^2 + a^2 = 15^2

2a^2 = 225

a^2 = 112.5

a=10.6 ( side of square )

perimeter of square = 4 a = 4 × 10.6 = 42.4

Answer 2

Answer:

measurement of one side of square is 10.6m and area of the square is 42.2m².

Step-by-step explanation:

Given,

Diagonal of square=15m

So, Area of square=1/2×d²

=1/2×15×15

=112.5

And Area=s²(s-->side)

So, 112.5=s²

√112.5=s

10.6=s

Perimeter=4s

=4×10.6

=42.2m²

Hence, measurement of one side of square is 10.6m and area of the square is 42.2m².
