Question

The length of a rectangle is 6cm more than its breadth If the perimeter of the rectangle is 60 cm find its length and width.Also find its area​

Answer 1

Answer:

Let the breadth of the rectangle be x

therefore, the length =x+6 cm

A/Q

Perimeter of the rectangle = 60cm

2( l+b) =60cm

2(x+x+6) = 60cm

2(2x+6) =60cm

4x+12. =60cm

4x. =60-12

4x. =48

x. =12

Length =12+6cm =18cm

Breadth. =12cm

Therefore,

Area =L * B =18*12cm = 216cm...

Answer 2

answer:

width=7 cm

length=6+x

=6+7

=13

area=42 cm sq

Step-by-step explanation:

given

length=6cm more than breadth

width=x

p=2(l+b)

60=2(x+6+x)

60=2x+12+2x

60=4x+12

60-12=4x

28=4x

28/4=x

7=x

length =6+x

=6+7

=13cm

area=l*b

=6*7

=42 cm sq
