Question

the area of a rectangle of breadth 3 cm is equal to the area of a square of side 9 cm.then the perimeter of the rectangle is​

Answer 1

Answer:

SIDE=9CM

AREA=9×9=81CM2

AREA OF RECTANGLE=81CM2

LENGTH=81/3

LENGTH=27CM

PERIMETER=2(L+B)

PERIMETER=2(27+3)

PERIMETER=2×30

PERIMETER=60M

Answer 2

The perimeter of rectangle is 60 cm

Step-by-step explanation:

Breadth of rectangle = 3 cm

Area of rectangle = $Length \times 3$

Area of square of side 9 cm =$9^2 = 81 cm^2$

$3 \times Length = 81$

Length =$\frac{81}{3}$

Length = 27 cm

Perimeter of rectangle = 2(l+b)=2(27+3)=60 cm

Hence The perimeter of rectangle is 60 cm
