4 strips of paneling 40cm long and 4cm wide are arranged to form a square. What is the area of the inner square in cm

The area of the square will be 640 sq cm.

Step-by-step explanation:

Given,

Number of strip = 4

Length (l) of each strip = 40 cm

Width (b) of each strip = 4 cm

To find the area of the inner square.

Formula

The area of rectangle = l*b

If the area of a square is A, each side will be √A

Now,

Area of each strip = 40*4 sq cm = 160 sq cm

Area of 4 strips = 160*4 sq cm = 640 sq cm

Hence,

The area of the square will be 640 sq cm.
