पर्याय

• 144 cm²

• 40 cm²

• 48 cm²

• 120 cm²

Answer 1

Perimeter of a rectangle is 26 cm, its length is 8 cm. ∴ Its area is 40 cm².

Explanation:

Given:

• Perimeter of rectangle = 26 cm
• Length of rectangle = 8 cm

We know the perimeter (P) of a rectangle is given by:

P = 2 × (Length + Breadth)

Substitute the given values: 

26 = 2 × (8 + Breadth)

26 = 16 + 2 × Breadth

2 × Breadth = 10

Breadth = 5 cm

Now, area (A) of rectangle is:

A = Length × Breadth

= 8 × 5

= 40 cm²
