In our previous segment of Class 6 Maths, we learnt how to find the area of an irregular shape. In this segment, we will look at some problems based on the area of a rectangle.

Point to remember

Whenever the area or the perimeter is to be calculated, the units of the dimensions given in the problem must be the same. If not, then convert the units before calculating the area or the perimeter.

Problem 1

Find the area of a rectangle whose length is 1.4 m and breadth is 9 cm.

Solution:

Length of the rectangle (L) = 1.4 m Breadth of the rectangle (B) = 90 cm

Since the units of the length and the breadth are different, we convert the length expressed in metres to centimetres.

1 m = 100 cm

So, 1.4 m = 1.4 x 100 cm

= 140 cm.

Hence, the length of the rectangle (L) = 140 cm

Now, the area of the rectangle = L x B

= 140 x 90

= 1260.

Thus, the area of the rectangle is 1260??².

Problem 2

Find the area of a rectangle whose length is 7 cm and breadth is 9 mm.
