Question

The width of a rectangle is 11 cm more than the length. The perimeter is 78cm. Find the width of the rectangle

Answer 1

Step-by-step explanation:

let length be x

then width is x+11

perimeter is 78cm

x+x+11=78

2x+11=78

2x=78-11

2x=67

x=67/2

x=33.5

Answer 2

The width of the rectangle is 25cm

Step-by-step explanation:

Let the length of the rectangle be x cm

width of the rectangle be (x+11)cm

Given perimeter is 78 cm

We know perimeter of the rectangle is $2\times$(length+width)

   $2\times$(x+x+11)=78

or 2x+11=$\frac{78}{2}$

or 2x+11=39

or 2x=28

or x=14

Length of the rectangle is x=14cm

Width of the rectangle is x+11=(14+11 )cm=25cm
