Question

4 squares of Perimeter 40 cm are arranged in a line what is the Perimeter of the newly obtain a rectangle

Answer 1

Answer:100cm

Step-by-step explanation:

As perimeter = 40cm

So,length of each side = 40/4

=10cm

Since they are arranged in a line so it forms a rectangle.

The length becomes 10cm and the breadth becomes 40 cm.

ATQ, PERIMETER = 2(l+b)

= 2 (10+40)

= 2(50)

= 100 cm
