The dimensions of the pool is 15m by10m
<h3>Area and perimeter of rectangle</h3>
A pool is rectangular in nature. If a rectangular swimming pool has an area of 150 square meters and a perimeter of 50 meters, then;
lw = 150
2(l+w) = 50
l + w = 25
where
l is the length
w is the width
From the equation 3
l = 25 - w
Substitute into 1
(25-w)w = 150
25w-w² = 150
w²-25w+150 = 0
w²-10w-15w+150 = 0
Factor
w(w-10)-15(w-10) = 0
w = 10 and 15
l = 150/10 = 15
Hence the dimensions of the pool is 15m by10m

Answer:
False
Step-by-step explanation:
12 + 24 = 36
6 * 3 = 18
Answer:
1. 100
2. 27 
3. 30
Step-by-step explanation:
Area = 
= x 
= 100
Volume = l x w x h
= 3 x 3 x 3
= 27
