Hey Ujjwal — ready when you are. Step 1: Identify the given width and the relationship between length and width. The width of the rectangular painting is given as 20 centimetres. The length is 1(1)/(4) times its width. Step 2: Calculate the length of the painting. First, convert the mixed fraction to an improper fraction: 1(1)/(4) = ((1 × 4) + 1)/(4) = (5)/(4) Now, calculate the length: Length = (5)/(4) × Width Length = (5)/(4) × 20 cm Length = 5 × 5 cm Length = 25 cm Step 3: Calculate the perimeter of the painting. The formula for the perimeter of a rectangle is P = 2 × (Length + Width). Substitute the calculated length and given width: P = 2 × (25 cm + 20 cm) P = 2 × (45 cm) P = 90 cm The perimeter of the picture is 90 cm. Send me the next one 📸
