the length of the rectangle is twice its breath if the perimeter is 84 meter find the length

Answer 1

Answer:

28m

Step-by-step explanation:

Let the breadth be x.

Then, length: 2x

Perimeter: 84m

Also, perimeter: 2(l+b)

: 2(2x+x)

: 2× 3x

: 6x

ATQ

6x = 84

x= 84/6

x=14

Breadth: x: 14m

Length: 2x: 2×14m: 28 m
