The length of a hall is 3 metres more than its breadth. If the area of the hall is 238 square metres, calculate its length and breadth.

I also study this question

Length is 3 m more than breadth.

Area of the hall = 238 m²

its length and breadth.​

Let the breadth of the hall be x m.

Length is 3 m more than breadth.

→ Length of the hall = (x + 3) m

Also given that,

Area of the hall = 238 m²

We know that,

Area of a rectangle = length * breadth

Hence,

→ 238 = (x + 3) * x

→ x² + 3x - 238 = 0

→ x² - 14x + 17x - 238 = 0

→ x(x - 14) + 17(x - 14) = 0

→ (x + 17)(x - 14) = 0

• x + 17 = 0

→ x = - 17

• x - 14 = 0

→ x = 14

Breadth of a hall cannot be negative. So, positive value is taken.

Therefore,

Length of the hall = x + 3 = 14 + 3 = 17 m.

Breadth of the hall = x = 14 m.

I hope it will help you.

answer: its c because when it has a magnet next to it it will move away from the mixture. hope this

step-by-step explanation:

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

spinner 1 spinner 2

1                     1

1                     2

1                     3

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
