Question

4. Find the area of a rectangle whose length is (2x + 7) units and breadth is (x - 5) units.​

Answer 1

Answer:

In this case, you would not get the exact value, in fact you will get the value of area in terms of the variable ' x ' .

So let us begin with the solution.

Length of the rectangle, denoted by l = ( 2x + 7 ) units

Breadth of the rectangle, denoted by b = ( x - 5 ) units

Now,

We are well familiar with the formula used to calculate the area of the rectangle.

Area of the rectangle, denoted by A = Length ( l ) * Breadth ( b )

A = l * b

A = ( 2x + 7 ) ( x - 5 )

A = 2x( x - 5 ) + 7( x - 5 )

A = 2x^2 - 10x + 7x - 35

A = (2x^2 - 3x - 35) sq. units

We are not given the value of ' x ' therefore, I cannot tell you the exact value of area.
