Question

Find the side and perimeter of a square whose diagonal is 10 cm.,​

Answer 1

Answer:

Side = 2.23cm

Perimeter = 8.92cm

Step-by-step explanation:

Diagonal = 10cm

Let 1 side be a, while other be b

Therefore, $a^{2}$ + $b^{2}$ = 10cm

             => $a^{2}$ + $a^{2}$ = 10cm .         [As all the side of a square are equal]

             => 2$a^{2}$ = 10cm

             => $a^{2}$ = 10cm

            => a = $\sqrt{10}$

            => a = 2.23

Hence, side of square = 2.23cm

Perimeter of square = 4a

=> 2.23 × 4 = 8.92cm

Hence, perimeter of square = 8.92cm
