Question

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

Answer 1

Step-by-step explanation:

PERIMETER = 4 × SIDE

= 4 × S = 80

= S = 20 CM

AREA OF SQUARE = AREA OF RECTANGLE

= 20×20 = 25 × BREADTH

= B = 400 ÷ 25

= B = 16

PERIMETER = 2(L+B)

= 2(25+16)

= 2 × 41

= 82

Answer 2

Step-by-step explanation:

Given:-. the perimeter of square = 80 cm

4 × side = 80 cm

side = 80 cm ÷ 4

side = 20 cm

And, area of square = area of rectangle

side × side = length × breadth

20 × 20 = 25 × breadth

breadth = 400/ 25

breadth = 16 cm

therefore, perimeter of rectangle = 2( l + b )

= 2(25cm + 16 cm)

= 2(41) cm

perimeter of rectangle = 81 cm
