Question

The area of a square is four times the area of a rectangle.The length of the rectangle is 25 cm and its breadth is one cm less than one fifth of its length.What is the perimeter of the square

Answer 1

Answer:

Step-by-step explanation:

Solution,

Length of rectangle=25cm

Given in the question,

Breadth is 1cm less than one/fifth of length

Length=25÷5

=5

=25-5( 1cm less than one fifth)-1

=19 cm

Area of the rectangle,

=Length×Breadth

=25×19

=475cm2

Area of square 4 times the area of the rectangle,

=475×4

=1900cm2

So, area of square

=1900cm2
