To find the area of the panel and the area covered by Shivangi’s picture, we first need to calculate the dimensions of the panel and then the areas.
The dimensions of the picture are given as 40 cm long and 28 cm wide. Since there is a 1 cm border on all sides, we will add 2 cm to both the length and the width of the picture (1 cm on each side).
Calculating the dimensions of the panel:
- Length of the panel = 40 cm + 2 cm = 42 cm
- Width of the panel = 28 cm + 2 cm = 30 cm
Now, we can find the areas:
Area of the panel:
Area = Length × Width
Area = 42 cm × 30 cm = 1260 cm²
Area covered by the picture:
Area = Length × Width
Area = 40 cm × 28 cm = 1120 cm²
In conclusion, the area of the panel is 1260 cm², and the area covered by the picture is 1120 cm².
