Answer:
(a) Length of the parking lot : 84 m
(b) Width of the pool: 82 m
Explanation:
(a) The perimeter of a rectangular parking lot is 290 m. If the width of the parking lot is 61 m, what is its length?
(b) The area of a rectangular pool is 7790 m². If the length of the pool is 7790 m². If the length of the pool is 95 m, what is its width?
Solve:
(a) The perimeter of a rectangular parking lot is 290 m. If the width of the parking lot is 61 m, what is its length?
Formula for perimeter: P = (L + W) × 2
Which;
P = Perimeter
L = Length
W = Width
Which also could be written as:
L + L + W + W = P
Hence, since it given that;
290 = P and W = 61
Then
We know that ;
61w + 61 w + L + L = 290
So we can add 61 + 61 or 61 × 2
which is 122.
Now we know that;
122 + 2L = 290
Solving for 2L:
122 + 2L = 290
122-122 + 2L = 290-122
2L = 168
L = 84
Hence, the length is 84.
Check Answer:
61 × 2 + 84 × 2 = 290

(b) The area of a rectangular pool is 7790 m². If the length of the pool is 7790 m². If the length of the pool is 95 m, what is its width?
Formula for area: A = Lw
Which;
A = Area
L = Length
W = Width
So, since we know the length we can just do 7790/95 to find Width
7790/95 = 82
Hence, the width of the pool is 82 m.
Check Answer:
A = Lw
A = 82 × 95
A = 7790m²
