The perimeter of a rectangular park is 200 feet. The length of the park is 40 feet longer than the width.Find the length of the

Leto [7]

$\green{ \boxed{\sf \: length \: \: = 70 \: \: feet}}$

Step-by-step explanation:

Let assume that,

Wide = x

So,

length = x + 40

Given,

perimeter = 200 feet

We know that,

Perimeter = 2(length + wide)

So,

$200 = 2(x + 40 + x) \\ = > \frac{200}{2} = 2x + 40 \\ = > 2x + 40 = 100 \\ = > 2x = 100 - 40 = 60 \\ = > x = \frac{60}{2} \\ = > x = 30 \: feet$

So length = x + 40 = 30 + 40 = 70 feet

Work out the value of x.

Len [333]

Answer:

67.5 degrees

Step-by-step explanation:

The angles at the center of the figure = 360 degrees

Therefore, 3x + x + 90 degrees = 360 degrees

simplifying:

4x + 90 degrees = 360 degrees

4x = 360 - 90

4x = 270 degrees

x = 270÷ 4

x = 67.5 degrees
