Examples on Rectangle

Here are some solved examples on the basic concepts of rectangle for your help.

Example 1: Find the area of the rectangular photo frame whose sides are 8 cm and 6 cm.

Solution:

Given,

• Length of Photo Frame = 8 cm
• Breadth of Photo Frame = 6 cm

Area of Photo Frame = Length × Breadth

                                  = 6 × 8 = 48 cm²

Thus, the area of the photo frame is 48 cm².

Example 2: Find the perimeter of the rectangular field whose sides are 9 m and 13 m.

Solution:

Given,

• Length of Rectangular Field = 9 m
• Breadth of Rectangular Field = 13 m

Perimeter of Rectangular Field = 2 × (l + b)

                                                  = 2 × (9 + 13) = 2 × (22)

                                                  = 44 m

Thus, the perimeter of the rectangular field is 44 m.

Example 3: Find the area and the perimeter of the room with a length of 12 feet and a breadth of 8 feet.

Solution:

Given,

• Length of room (l) = 12 feet
• Breadth of room (b) = 8 feet

Area of Room = Length × Breadth

                        = 12 × 8 = 96 feet²

Perimeter of Room = 2 × (l + b)

                               = 2 × (12 + 8) = 2 × 20

                               = 40 feet

Thus, the area of the room is 96 feet², and the perimeter is 40 feet.

Example 4: Find the length of the diagonal of the rectangle whose sides are 6 cm and 8 cm.

Solution:

Given,

• Length of rectangle (l) = 6 cm
• Breadth of rectangle (b) = 8 cm

Length of diagonal (d) = √( l² + b²)

d = √( 8² + 6²) 

d = √ (64 + 36) = √(100)

d = 10 cm

Thus, the length of the rectangle is 10 cm

Rectangle is a polygon with four sides, whose all four of its angles are equal to 90 degrees. The opposite sides of a rectangle are both equal in length and run parallel to each other.
