The area of a rectangular parking lot is 4947 m2. If the length of the parking lot is 97 m, what is its width?

Width of the parking lot:

The perimeter of a rectangular pool is 304 m.
If the width of the pool is 68 m, what is its length?

Length of the pool:

1. width = 51 m

2. length = 84 m

Step-by-step explanation:

So remember, the area is (length * width).

It is given that the length is 97, and the area is 4947.

So plug this into a formula:

length * width = area

97 * width = 4947

Solve using inverse operations;

97 * width = 4947

/97               /97

width = 51m

The perimeter of a rectangle can be found by doing, (2 * (length + width)).

The width is given, it is 68m. The perimeter is also given, 304m. So just form an equation using this information:

2 * ( length + width) = perimeter

2 * (length + 68 ) = 304

Distribute;

2 * ( length + 68) = 304

2 length + 136 = 304

Inverse operations;

2length + 136 = 304

               -136    -136

2length = 168

/2             /2

length = 84m

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
