The perimeter of a rectangle is 96 ft and the width is 22 ft what is the length of the rectangle
UNO [17]

The length of the rectangle is 26ft.

What is the perimeter of a rectangle?

  • The sum of all sides of a rectangle is the perimeter of the rectangle.
  • A rectangle has two equal lengths and two equal widths.
  • Therefore, the perimeter 'P' of a rectangle is the sum of two equal lengths and two equal widths.
  • That is, 'P=2l+2w' where 'l' is the length and 'w' is the width of the rectangle.

<h3>What is the length of the rectangle with perimeter 96ft and the width 22ft?</h3>

The perimeter of a rectangle is, P = 96 ft.

The width of the rectangle is, w = 22ft.

As we know the perimeter P of a rectangle is given by the formula, P=2l+2w

Therefore, substituting the values in the equation we get,

P = 2l + 2w

96 = 2l + 2*22

96 = 2l + 44

2l = 96 - 44

2l = 52

l = 52/2

l = 26

Hence, the length of the rectangle is 26ft.

Why is x = 4 a solution to the proportion 15/x = 56/16 A) because 56 divided by 14 equal to 4. B) because 56 divided by 16 is eq
melamori03 [73]

Answer:

The given proportion is

   \frac{14}{x}=\frac{56}{16}\\\\14 \times 16=56\times x\\\\x=\frac{14 \times 16}{56}\\\\x=\frac{16}{4}\\\\x=4

Substitute , x=4 in the equation

  \frac{14}{4}=\frac{56}{16}\\\\56 \times 4=14 \times 16\\\\224=224

Option D

Because if you substitute 4 into the equation for x and cross multiply, you get 224 = 224.
