Question

The ares of a square is 289cm square. find its perimeter and the length of the diagonal

Answer 1

Answer:

P=68.

Step-by-step explanation:

a=289 hey u will understand that I think

Answer 2

Answer:

$\sqrt{289 } = \sqrt{17 \times 17} = \sqrt{17 {}^{2} }$

now the square root and square power will be cancelled but don't show that

so 17 is the square of 289

since we know side ×side is area of square

so 17 is the side of the square now perimeter is 4×17cm

= 68cm is the perimeter

diagonal will be hypotenuse

so

hy²=b²+p²

hy²=289+289

hy²=578

hy=√578

hy=24.04 ans
