Question

Match the following parameters of a square of side 10 cm with their respective values.

• A. 100 $c{m}^2$
• B. 40 cm
• C. 10$\sqrt{2}$ cm

Answer 1

Let each side of the square be $a$ cm.
Hence, the area of the square = $a^2$ = ${10}^2$ $c{m}^2$ = 100 $c{m}^2$,
The perimeter of the square = 4a = 4$\times$10 cm = 40 cm,
The length of the diagonal of the square = a$\sqrt{2}$ = 10$\sqrt{2}$ cm.
