Question

Perimeter of rectangle 28 cm. Length of the rectangle is 12 cm. Find the area of
rectangle​

Answer 1

Answer:

192cm^2

Step-by-step explanation:

First

perimeter =l+b

or,28=12+b

or,28-12=b

b=16

Again,

Area=l×b

=12×16

=192cm^2

Answer 2

Answer:

area = 24 cm^2

Step-by-step explanation:

length of rectangle = 12 cm

perimeter =28cm

let the breadth =X

according to condition —

perimeter of rectangle= 2(length+breadth)

=>28 = 2(12 + X)

=>28/2= 12+X

=>14= 12+X

=>12-14=X

=> X=2

so breadth =2cm

area of rectangle = Length x Breadth

= (12 x 2)cm

= 24 cm^2
