Question

The length of a rectangular hall is 4 metres less than three times the breadth of the hall. What is the length, if the breadth is 6 metres

Answer 1

ANSWER:

• Length of rectangle = 6m

GIVEN:

• length of a rectangular hall is 4 metres less than three times the breadth of the hall.
• Breadth of the rectangle = 6 metres.

TO FIND:

• Length of rectangle.

SOLUTION:

Breadth of rectangle = 6 m

Length of rectangle is 4 m less then 3 times the breadth of the wall.

Length = 3(6-4) m

= 3(2) m

= 6 m

Length of rectangle = 6m

ADDITIONAL INFORMATION:

If the question ask about finding the area of rectangle then :

Formula:.

• Area of rectangle = (length)(Breadth)

Here:

Length = 6 m

Breadth = 6 m

Area of rectangle = (6*6)

= 36 m²

NOTE:

Some important formulas:

Area of Square = (Side)²

Area of rectangle = Length*Breadth

Area of rhombus = Base*Altitude

Area of parallelogram = Base*Altitude

Area of Triangle = (Base*Altitude)/2
