Question

the breadth of a rectangle is half of its length parameter is 30 and find length and area ​

Answer 1

Answer:

Let length = l m

Breadth = l/2

2(l/2 + l) = 30

3/2 l = 15

l = 10 m

Area = 5 x 10 = 50 sq m.

Answer 2

Given,

• The Breadth of Rectangle is Half of It's Length.
• The Perimeter of Rectangle = 30 units

To Find,

• The Length of Rectangle.
• The Area of Rectangle.

Solution,

Let's,

The Breadth of Rectangle = X

So,

The Length of Rectangle = 2X

The Perimeter of Rectangle = 30 units

→ 2 × (Length + Breadth) = 30 units

→ 2 × (2X + X) = 30 units

→ 2 × 3X = 30 units

→ 3X = 30/2 units

→ 3X = 15 units

→ X = 15/3 units

→ X = 5 units

The Breadth of Rectangle = X

→ The Breadth of Rectangle = 5 units

The Length of Rectangle = 2X

→ The Length of Rectangle = 2(5 units)

→ The Length of Rectangle = 10 units

The Area of Rectangle = Length × Breadth

→ The Area of Rectangle = 10 units × 5 units

→ The Area of Rectangle = 50 Square units

Required Answer,

The Length of Rectangle = 10 units

The Area of Rectangle = 50 Square units
