Answer 2

Given:-

• Length of a rectangle is twice the breadth.
• Perimeter of a rectangle is 30 cm.

⠀

To find:-

• Area of a rectangle.

⠀

Solution:-

Let,

• the Length be 2x and breadth be x.

⠀

According to the question

→ Perimeter of a rectangle = 2(l + b)

→ 2(2x + x) = 30

→ 4x + 2x = 30

→ 6x = 30

→ x = 5c

⠀

Therefore,

• length = 2x = 2 × 5 = 10 cm
• breadth = x = 5cm

⠀

Now,

→ Area of a rectangle = l × b

→ 10 × 5

→ 50 cm²

⠀

Hence,

• the area of a rectangle is 50 cm².
