Question

the length of a rectangle is 12 more than its breadth. If the perimeter is 44 cm , then the area is___​

Answer 1

Step-by-step explanation:

let the breadth of rectangle be x

and length=x+12

perimeter of rectangle=2(l+b)

44cm=2(x+12+x)

44÷2=2x+12

22=2x+12

22-12=2x

10=2x

x=5

now, breadth=5cm

and length=x+12=5+12=17cm

so, area of rectangle=l×b=5×17=85cm2

Answer 2

Answer:

perimeter of rectangle is equals to 2( l + b)=44

(l+b)=44/2

=22

(12+ b)=22

b=22-12

=10

now the area of rectangle =l×b

l=12

b=10

therefore area becomes 12×10= 120
