The breadth is x.
The length is 2 m more than twice the breadth, so it's 2x+2.
The perimeter of a rectangle is twice the sum of the length and the breadth. The perimeter is 154 m.

The length of the swimming pool is 52 m, the breadth is 25 m.
Answer:
113

Explanation:
The formula for volume of a cylinder is π

h
Fill in with your values:
π = 3.14
r = 3
h = 4
3.14

4 = 3.14(9)4 = 3.14(36) = 113.04
Round down to 113
The values needed to make each expression a perfect square trinomial is 4 and 25
You would use the cosine rule for this as you have 2 lines and are given the angle between them
The angle can be figured out easily as the clock has 12 equal components, meaning each component is 360/12 which is 30
As there are 5 components between A and B the angle is 30*5 =150
You can plug all of this into the cosine rule
a^2= b^2+c^2-2bcCos(A)
So a = sqrt( 10^2 +7^2 -(2*10*7) cos150)
a=16.4 to 3 sf
