The length of a rectangular swimming pool is twice as long as its width. If the perimeter of the pool is

Mathematics

Nitella [24]3 years ago
4 0

The perimeter of a rectangle is the sum of its sides, which are two widths and two lengths:

p=w+w+l+l

Since the length is twice the width, we have l=2w, and the formula for the perimeter becomes

p=w+w+2w+2w=6w

So, we have

6w=120 \iff w=\dfrac{120}{6}=20

Find the dimensions of a deck which will have railings on only three sides. There is 28 m of railing available and the deck must
Roman55 [17]

Answer:

The largest possible area of the deck is 87.11 m² with dimensions;

Width = 9.33 m

Breadth = 9.33 m

Step-by-step explanation:

The area of a given dimension increases as the dimension covers more equidistant dimension from the center, which gives the quadrilateral with largest dimension being that of a square

Given that the railings will be placed on three sides only and the third side will cornered or left open, such that the given length of railing can be shared into three rather than four to increase the area

The length of the given railing = 28 m

The sides of the formed square area by sharing the railing into three while the fourth side is left open are then equal to 28/3 each

The area of a square of side s = s²

The largest possible area of the deck = (28/3)² = 784/9 = 87.11 m² with dimensions;

Width = 28/3 m = 9.33 m

Breadth = 28/3 m = 9.33 m.
