Question

Find the length of a boundary of a square field whose area is 784m

Answer 1

Ar of square =784
S ×S =28 ×28
S=28m
Length of boundary is equal to perimeter of square
So
Lenth of boundary =4S
=4×28
=112m

Answer 2

Answer:

area of square = 784

S×S = 28 × 28 = 4×4 =28 m

Step-by-step explanation:

so, length of boundary = 4S

=4× 28

= 112 ans
