The length of a rectangle board is 10 centimeters longer than its width. The width of the board is 26 centimeters. The board is
Troyanec [42]

Answer:

Area of each piece = 104 cm^{2}

Possible dimensions are 26 cm by 4 cm, 13 cm by 8 cm.

Step-by-step explanation:

Given that:

Dimensions of the rectangular board as:

Length of the board is 10 cm longer than its width.

Width of the board = 26 cm

Length of the board = 26 + 10 = 36 cm

The rectangular board is divided into 9 equal pieces.

To find:

Area of each piece and

the possible dimensions of each piece = ?

Solution:

First of all, let us calculate the area of bigger rectangular board.

Area of a rectangle is given by the following formula:

Area = Length \times Width

Area = 26 \times 36 cm^2

Area of each smaller rectangle = \frac{26\times 36}{9} = 104\ cm^2

To find the possible dimensions, we need to find the factors of 104.

104 = 26 \times 4

104 = 13 \times  8

Therefore, the Possible dimensions are 26 cm by 4 cm

and

13 cm by 8 cm.

The Recreation Center has an L-shaped pool. One pool is 8 meters by 6 meters. The other part is 12 meters by 6 meters. The whole
defon

Answer:

480m³

Step-by-step explanation:

The entire pool have the same depth which is 4metres

Since the pool is L shaped, we will find the volume of each part and add them together to get the volume of the entire pool.

Using the formula for calculating volume of a rectangular box

V = lwh

L is the length

w is the width

h is he height

For the first pool.

Length = 8m

Width = 6m

Height = 4m (depth)

Volume = 8×6×4

Volume = 192m³

For the other pool.

Length = 12m

Width = 6m

Height = 4m (depth)

Volume = 12×6×4

Volume = 288m³

Volume of the entire pool = 192+288 = 480m³
