Shivangi had a picture that is 40 cm long and 28 cm wide in the center of the panel leaving a border of 1 cm on all sides. Find the area of the panel and cover by the picture.

The area of the picture can be obtained by multiplying its length and breadth.

Answer: The 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 the picture.

Explanation:

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

Thus, area of the panel is 1189 cm² and the area of the picture is 1120 cm².
