Question

length of rectangle is 2cm more than twice its breath .if the perimeter of the rectangle is 28cm , find its leanth and breath​

Answer 1

Let breadth=x

Length=2x+2cm

Perimeter=28cm

❥Perimeter=2×(l+b)

=>2×[x+(2x+2)]=28

=>2(x+2x+2)=28

=>(2)(x)+(2)(2x)+(2)(2)=28

=>2x+4x+4=28

=>(2x+4x)+(4)=28

=>6x+4=28

=>6x+4=28

Then Subtract 4 from both sides.

=>6x+4−4=28−4

=>6x=24

Afterwards Divide both sides by 6

=>6x/6=24/6

x=4

Breadth=4cm

Length=2x+2cm

=2×4+2

=10cm

Answer 2

Answer:

LENGHT = 10CM

BREADTH = 4CM

Step-by-step explanation:

breadth = (2x+2)

We know that

Perimeter =  l + l + b + b

28x = 2x+2+2x+2+x+x

28x = 6x + 4

6x = 28 - 4

x = 24 / 6

x = 4cm

breadth = 4cm

length = 2x + 2

L = 2(4) + 2

L = 8 + 2

L = 10cm

Length = 10cm
