Question

the areas of a square and a rectangle are same.the perimeter of the square is 80 cm,if the length of the rectangle is 25 cm find its breadth and perimeter

Answer 1

Answer:

let the side of square be x cm

perimeter of square = 80 cm (given)

4 x = 80

x = 20 cm

area of square = side * side = 20 * 20 = 400 cm sq.

area of square = area of rectangle (given)

area of rectangle = 400 cm sq.

length * breadth = 400

25 * breadth = 400

breadth of rectangle = 16 cm

perimeter of rectangle = 2(l+b)

=2(25+16)

=2(41)

perimeter of rectangle = 82 cm
