Question

The perimeter of rectangle is 40cm.
The length of the rectangle is more than
double its breadth by a find the
length and breadth.
.
​

Answer 1

Answer:

Length = 14 cm and breadth = 6 cm.

Step-by-step explanation:

$\huge\tt\red{Given \: that:-}$

• The perimeter of a rectangle is 40 cm.
• The length of rectangle is more than double its breadth by 2 cm.

$\huge\tt\ \blue{To \: find:-}$

• Find the length and breadth of rectangle .

$\huge\tt \green{Solution:-}$

Perimeter of rectangle = 40 cm (given)

Condition :- length = 2×breadth +2

==> 1 = 2b +2

Perimeter P = 2(l+b) = 40 cm

==> 2(2b + 2 + b) = 40 cm

==> 2(3b + 2) = 40 cm

==> 6b = 40cm - 4

==> 6b = 36cm

==> b = 36cm/6

==> b = 6cm.

.°. breadth = 6 cm.

Now finding Length

L = 2 × 6 + 2

==> 12 + 2

==> 14 cm.

.°. Length = 14 cm.

According to the question ,we find

length (L) = 14 cm.

Breadth (b) = 6 cm Ans.
