Step-by-step explanation:
The perimeter of a rectangle = 22 cm
Breadth of rectangle = 4 cm
Length of rectangle = ?
Let the Length of the rectangle be 'L' cm.
• According to the Question :
→ Perimeter of rectangle = 2(Length + Breadth)
→ 22 = 2(L + 4)
22= 2L + 8
22-8=2L
→14 = 2L
→14÷2=L
→7 cm = L
..Length of the rectangle is 7 cm
• VERIFICATION:
→ 22 = 2(L + 4)
22 = 2(7 + 4)
→ 22 = 2 × 11
Hence, Verified!
