Question

the area of a square is 900cm square find the length of the diagonal and perimeter of square​

Answer 1

Answer:

900

Step-by-step explanation:

A=a2

d=2a

Solving ford

d=2A=2·900≈42.42641

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

find the area of square is 900 CM square. and the length of diagonal and perimeter of square
