Step-by-step explanation:
Length ( l ) = 3.2 cm
Breadth ( b ) = 2.4 cm
Perimeter = 2 ( l + b )
= 2 ( 3.2 + 2.4 )
= 2 ( 5.6 )
= 11.2 cm
Area = l × b
= 2.4 × 3.2
= 7.68 cm^2

Question -:
Find the perimeter,area and length of diagonal of a rectangle having :
length = 3.2cm, breadth = 2.4cm
Explanation -:
Given :
- Length of a rectangle = 3.2 cm
- Breadth of the rectangle = 2.4 cm
Need to find :
- Perimeter
- Area
- Diagonal
Solution :
First we will calculate the Perimeter
Substituting the value we get
→ 2 (3.2 + 2.4)
→ 2 × 5.6
→ 11.2 cm
- Perimeter = 11.2 cm
Now we will calculate the Area
Substituting the value we get
→ (3.2 × 2.4) ²
→ 7.68 cm ²
- Area =7.68 cm ²
Now we will calculate the diagonal
Substituring the value we get
- Diagonal = 4 cm
