Question

The area of a rectangle of breadth 3 cm. is equal to the area of a square
of side 9 cm. Then perimeter of the rectangle is
(b) 60 cm (c) 63 cm (d) 65 cm
(a) 56 cm
​

Answer 1

Answer:

60 cm

Step-by-step explanation:

Let the length of the rectangle be 'L'.

Given, area of square = area of rectangle

=> side^2 = length x breadth

=> 9^2 = L x 3

=> 81/3 = L

=> 27 = L

Therefore,

Perimeter of rectangle=2(length+breadth)

Perimeter of rectangle = 2(27 + 3) = 2(30)

Perimeter of rectangle = 60 cm

Using:

Area of square = side^2

Area of rectangle = length x breadth

Perimeter of rectangle=2(length+breadth)

Answer 2

Answer:

Are of square 9×9=81

So, L = 81/3=27

PERIMETER =2(27+3)=2×30= 60 CM

SO ANS IS (b) 60 cm
