Question

9. The adjacent sides of a rectangle are (3a +262) units and (262 – 4a) units, respectively. Determine the area of the rectangle. -​

Answer 1

Answer:

The area of the rectangle is= -12a^2-262a+68644

Step-by-step explanation:

The adjacent sides of a rectangle are (3a+262) units and (262-4a) units

So the length of the rectangle is= (3a+262) unit

And the breadth of the rectangle is= (262-4a) units

So, the area of the rectangle is= length×breadth

= (3a+262) ×(262-4a) square unit

= 786a -12 a^2+68644-1048a square unit

= -12 a^2-262a+68644 square unit
