Test: How Many Squares? - Class 5 MCQ

The area of the whole square = 16 square cm

The shaded portion divides the square into half. This means that the area of the shaded portion = 1/2 of 16 square cm = 8 square cm.

Length of a boundary is called perimeter. 

- The correct answer is B: Area.
- The area measures the space enclosed within the boundaries of a plane figure, such as a rectangle or circle.
- It is expressed in square units, like square meters or square feet.
- The perimeter, on the other hand, is the total distance around the boundary of a figure.
- Volume measures space in three-dimensional figures.
- Diameter is a term used specifically for circles, representing the distance across the circle through its center.

Area of 1  = 3 sq. units
Area of shape P = 10 sq. units
Area of shape Q = 11 sq. units.
Area of shape R = 10 sq. units.
Area of shape S = 10 sq. units.
So, shape Q has largest area   

There are 6 × 4 = 24 squares and each square has an area of = 1cm². So, the area of rectangle =6 × 4 × 1 = 24cm².

There are 2 × 4 = 8 squares and each square has an area of 1m² So, the area of rectangle = 8 m². 

Calculate no. of shaded boxes. It comes out to be 21. And each box has area of 1m². So the area of shaded region becomes 21m².

Side of square = 1 cm
Perimeter of given shape = 18 cm

No. of shaded boxes = 28, No. of unshaded boxes = 60

So, area of unshaded region = 60 m².

Note: To count the number of shaded/unshaded boxes quickly, the student can use the concept of group counting and count the number of columns (8 boxes = 1 column) + extra boxes.

There should be 12 blocks in a figure to get an area of 12m².

In option (c), there are 2× 6 = 12 blocks in figure.
