Question

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:

Answer 1

The answer for number 1 is width = 51 m

The answer for number 2 is length = 84 m

Explanation:

Answer 2

1. width = 51 m

2. length = 84 m

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
