Question

1. a) The side of a square is 12 cm. Find (1) its area, 2)perimeter,3) length of the diagonal​

Answer 1

Answer:

Step-by-step explanation:

Side= 12 cm

Area of the square= Side xSide

                                = 12x12=144 sq. cm

Perimeter = 4xS= 4x12=48 sq. cm

Length of diagonal= sq. root of 2xSide= sq. root of 2X12= 12 sq. root 2 cm Ans.

Answer 2

Finding the area, perimeter, and diagonal length of square:

Step-by-step explanation:

$\ Given \ that:$

$\ Side \ of \ square: \ \ 12 \ cm$

$\ Find:\\\ i) \ Area\\\ ii) \ Perimeter\\\ iii) \ diagonal \ length$

$\ formula:$

i)

$Area = \ Side \times \ Side \\\\\ Area= \ 12 \times\ 12 \\\\\ Area=144 \ cm^2$

ii)

$\ Perimeter = \ 4 \times \ sides \ of \ square\\\\\ Perimeter = \ 4 \ times \ 12\\\\\ Perimeter = 48$

iii)

$\ Length \ of \ diagonal (d) =\sqrt{2} \ a \\\\\ Length \ of \ diagonal (d) = \sqrt{2} \times 12\\\\\ Length \ of \ diagonal (d) = 1.414 \times 12\\\\\ Length \ of \ diagonal (d) =16.968$
