Question

what will be the length of side of a square whose area is 361 sq. cm?​

Answer 1

Answer:

19

The area of a square is its length times its width:  l x w  =  361

Since the length of a square is the same as its width, replace 'w' with 'l':  l x l  =  361

     l x l  =  l²  =  361     --->   l  =  √361       --->   l  =  √361       --->     l  =  19 .

Answer 2

Solution!!

The area of square is given. We have to find the length of the side of the square. You should know the formula to find the area of the square. Using that formula, we can find the side of the square.

Area = 361 cm²

→ Area = (Side)²

361 cm² = (Side)²

Side = √361 cm²

Side = 19 cm

The length of the side of the square whose area is 361 cm² is 19 cm.

More formulae:-

→ Area of the rectangle = Length × Breadth

→ Perimeter of triangle = Sum of the three sides

→ Area of the square = πr²

→ Circumference = 2πr

→ Perimeter of rectangle = 2(Length + Breadth)
