Question

. The length of a rectangle is twice the breadth. If its perimeter is 60m ,then fnd its length.

Answer 1

Answer:

Lenght=20m

Step-by-step explanation:

Lenght =2x

Breadth=x

Perimeter =60 m

60m=2(l+b)

60=4x+2x

60=6x

X=10

Answer 2

Answer:

Breadth= x

Length=2x

Perimeter of Rectangle=2(l+b)

ATQ

2(x+2x)=60

2(3x)=60

6x=60

x=60/6

x=10

Thus, Length=2x=10×2=20m

Breadth=x=10m
