Question

the perimeter of a rectangular is 40 cm . the length of the rectangle is more than double it's breath by 2 find lenth and breath.​

Answer 1

Answer:

Length=14cm and Breadth=6cm

Step-by-step explanation:

Perimeter of a rectangle=2×(l+b)

Given

let breadth be x

b=x

Length is more than double it's breadth by 2

l=2x+2

Perimeter=40cm

2×(2x+2+x)= 40cm

Multiplying all in bracket with 2 we get

4x+4+2x=40cm

6x+4=40cm

6x=40cm-4

6x=36cm

x=36÷6

x= 6cm

So breadth =6cm

length =2x+2 where x=breadth

length=14 cm

Hope you understand it
