the perimeter of a rectangular park is 550m. The length is 35m longer than the width. Find the length and width of the park

Answer 1

Let's call the width of the park "x".

According to the problem, the length is 35m longer than the width, so the length is:

x + 35

The perimeter is the sum of all four sides of the rectangle, so we can write the equation:

Perimeter = 2(Length + Width)

Substituting in the values we know:

550 = 2(x + 35 + x)

Simplifying:

550 = 2(2x + 35)

275 = 2x + 35

240 = 2x

x = 120

So the width of the park is 120m.

To find the length, we can use:

Length = Width + 35

Length = 120 + 35

Length = 155

So the length of the park is 155m.

Therefore, the dimensions of the park are:

Width = 120m

Length = 155m

Answer 2

polly is 28 years older than her duaghter molly. Pollys mother dolly is four times molly's age. The sum of their threw ages is 130. How old is molly

Answer 3

Let's start by using variables to represent their ages:

- Let's call Molly's age "M"
- Then, we know that Polly is "28 years older than her daughter", so her age is "M + 28"
- Finally, we know that Dolly is "four times Molly's age", so her age is "4M"

We also know that "the sum of their three ages is 130", so we can write an equation:

M + (M + 28) + 4M = 130

Simplifying this equation, we get:

6M + 28 = 130

Subtracting 28 from both sides:

6M = 102

Dividing both sides by 6:

M = 17

Therefore, Molly is 17 years old.
