## How do you find the length when you have the area and width?

Substitute the values of Area in the formula ‘A = l × w’ and simplify to find width ‘w’ in the form of length ‘l’.

**What is the perimeter of the area is 72?**

### What is the length of a rectangle whose area is 8 and whose width is half its length?

If the width of a rectangle is 8 inches, and the length is half the width, what is the area of the rectangle in square inches? Explanation: the length of the rectangle is half the width, and the width is 8, so the length must be half of 8, which is 4.

**How do you find the missing length?**

The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two.

#### What is the perimeter of a protractor?

The perimeter of a protractor is. πr. πr + 2r.

**How do you find the length of an area?**

To find Length or Breadth when Area of a Rectangle is given

- When we need to find length of a rectangle we need to divide area by breadth.
- Length of a rectangle = Area ÷ breadth.
- ℓ = A ÷ b.
- Similarly, when we need to find breadth of a rectangle we need to divide area by length.
- Breadth of a rectangle = Area ÷ length.

## How do you find length Width Height and Area?

Multiply the length by the width and you’ll have the square feet. Here’s a basic formula you can follow: Length (in feet) x width (in feet) = area in sq. ft.

**How do you find the length and width given the perimeter?**

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

### What is triangular area?

The area of a triangle is defined as the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 × b × h.
