Question

If the length of rectangle is X + 2 (cm and breadth is X + 1 cm find the area of the rectangle

Answer 1

Answer:

x² + 3x + 2 cm²

Explanation:

Given:

Length = (x + 2)cm

Breadth = (x + 1)cm

To find:

Area of the rectangle.

Solution:

Area = Length × Breadth

Since, (x + a)(x + b) = x² + (a + b)² + ab

=> (x)² + (2 + 1) × (x) + 2 × 1

=> x² + 3x + 2 cm² is the area of the rectangle.
