Shivangi had a picture that is 40 cm long and 28 cm wide in the centre of the panel leaving a border of 1 cm on all side. Find the area of the panel and cover by the picture.
Area of picture can be obtained by multplying its length and breadth.
Answer: Area of the panel is 1189 cm2 and the area of the picture is 1120 cm2.
Let's find the area of the panel and cover by the picture.
Let's draw a rough diagram of the picture with panel
Length of the picture = 40 cm
Therefore the length of the panel = (40 + 1) cm = 41 cm
Breadth of the picture = 28 cm
Therefore the breadth of the panel = (28 + 1) cm = 29 cm
Area of the panel = Length × Breadth
= 41 cm × 29 cm = 1189 cm2
Area of the panel covered by picture is the area of the picture.
Area of the picture = Length × Breadth
= 40 cm × 28 cm
= 1120 cm2
