Question

# The length and breadth of a rectangle are (2x – 8) cm and (5x – 7) cm. Find the area of the rectangle.

Hint:

### The concept used in the question is area of rectangle.

○ The area of the rectangle is the product of sides.

## The correct answer is: Hence, the area of the rectangle is 10x2 - 54x + 56 sq.cm.

### Answer:

- Step-by-step explanation:

○ Given:

Two sides of a rectangle

(2x – 8) cm and (5x – 7) cm.

○ Step 1:

We know, that the area of a rectangle is the product of its sides

i.e area = side side

So,

Area = (2x – 8) (5x – 7)

= 2x (5x -7) - 8(5x-7)

= 10x^{2} - 14x - 40x + 56

= 10x^{2} - 54x + 56 sq.cm

- Final Answer:

Hence, the area of the rectangle is 10x^{2} - 54x + 56 sq.cm.

^{2}- 14x - 40x + 56

^{2}- 54x + 56 sq.cm
