Question

The perimeter of a rectangle is 34 units. Its width is 6.5 units.
1. Write an equation to determine the length (L) of the rectangle.
2. Find the length of the rectangle.

Answer 1

Answer:

1. 2(L + 6.5) = 34

2.length of rectangle is 10.5 units

Step-by-step explanation:

1.Given that the formula of the perimeter is P = 2L+ 2w / P = 2(L+ w). Then substitute the following value into the formula:

P = 34 units

w = 6.5 units

34 = 2(L+6.5)

2.Then solve it:

2(L+6.5) = 34

L + 6.5 = 17

L = 10.5 units

Answer 2

Answer:

Length of the rectangle= 10.5 units

Step-by-step explanation:

Perimeter of the rectangle is the sum of all the four sides of it, that can be find by the formula:

Perimeter of the rectangle = 2(Length+Width)

For,

$Perimeter=34 units\\\\Width= 6.5 units$

Putting in the formula:

$34=2(Length+6.5)\\\\34/2=Length+6.5\\\\17=Length+6.5\\\\Length=17-6.5\\\\Length=10.5 units$

The Length of the rectangle= 10.5 units
