Question

Area of square is 900cm square. Find its side

Answer 1

Step-by-step explanation:

Sqrt(900)=30 ,so each side length is 30 cm. The perimeter is 4*30=120 cm.

Pythagoras Theorem says that squaring the two shorter sides of a right angle triangle and adding them will give the longest side squared (a^2 + b^2=c^2).

So 900+900=1800. Therefore, the diagonal is sqrt(1800). This simplifies to 30*sqrt(2) cm which is the exact lenth of the diagonal. Its decimal approximation is 42.42640687 cm

Answer 2

Answer:

Area of square = 900 cm²

(Side²) = 900

Side =

$\sqrt[]{900}$

= 30 cm

Perimeter = 4 × Sides

= 4 × 30

= 120 cm
