Question

find the length of a side of a square whose perimeter is 10.4 cm​

Answer 1

Answer:

4a = 10.4

a=10.4/4

a=2.6

Answer 2

In the above question, the given value is,

Given that,

Perimeter $=10.4cm$

Find the length of a side of a square.

To find the length of a square we have to use the formula of the perimeter,

Therefore the perimeter is equal to four times side.

$P=4\times a$

Thus side of the square is equal to the perimeter upon four.

$a=\frac{P}{4}\\a=\frac{10.4}{4}\\a=2.6cm$

Hence the length of a side of a square is 2.6cm.
