Question

the length of a rectangle is 3 more than its width .if the perimeter of the rectangle is 30 cm then find the length and breadth of rectangle?
​

Answer 1

Answer:

The answer is:- Width -6cm, Length= 9cm

Step-by-step explanation:

Let width of rectangle be X

then, length will be = X+3

perimeter of rectangle = 2(l+b)

2(X+3+X)=30

2(2x+3) =30

4x+6=30

4x=24

X = 24/4

X= 6cm

Breadth/width = 6cm

Length = 9cm

Answer 2

Answer:

Explanation:

Let the width be xand length be(x+3) .

now, we have,

Perimeter=2(l+w)

58cm=2(x+x+3)

4x+6=58cm

4x=52cm

x=524cm

∴x=13cm

So, width = x =13 cmand,

length = x+3 = 13 cm +3 =16 cm
