Question

find the perimeter , diagonal and area of a square having each side measure 5 cm​

Answer 1

Answer:

The perimeter of a square of the side $a=5cm$ is $20cm$ , its area is $25cm^{2}$ and the diagonal length is $7.07cm$

Step-by-step explanation:

A square is a four-sided polygon that has all four sides equal in length and the angle between sides are $90$⁰

The perimeter of a square is the total distance covered through its four sides

since all the sides are equal the perimeter is $=4a$

where $a$ is the length of the side

here $a=5cm$

so perimeter $=4*5=20cm$

The area of the square is given by the formula $=a^{2}$$=5*5=25cm^{2}$

using the Pythagoras theorem the diagonal is the hypotenuse

so diagonal length $=\sqrt{5^{2} +5^{2} } =\sqrt{50} =7.07cm$
