Answer 1

Answer:

Answer:

Their length and breadth are:

Length = 30 cm

Breadth = 15 cm

Step-by-step explanation:

Given that:

The length of rectangle is double its breadth.

The perimeter of a rectangle is 90 cm.

To Find:

The length and breadth.

Let us assume:

Breadth of a rectangle = x cm

Length of a rectangle = 2x cm

Formula used:

Perimeter of a rectangle = 2(Length + Breadth)

Finding their length and breadth:

→ Perimeter = 2(Length + Breadth)

Substituting the values.

→ 90 = 2(2x + x)

→ 2x + x = 90/2

→ 3x = 45

→ x = 45/3

→ x = 15

Their length and breadth:

Length = 2x = (2 × 15) = 30 cm

Breadth = x = 15 cm
