Multiple Choice

Find the area of this figure.

• Area of the figure= Area of rectangle + Area of rectangle = (length x breadth) + (length x breadth) = (5 cm x 4 cm) + (3 cm x 4 cm) = $$20cm^2\ +\ 12cm^2=32cm^2$$  

• Area of the figure= Area of rectangle + Area of square = (length x breadth) + (side x side) = (5 cm x 4 cm) + (3 cm x 5 cm) = $$20cm^2\ +\ 15cm^2=35cm^2$$  

• Area of the figure= Area of rectangle + Area of rectangle = (length x breadth) + (side x side) = (4 cm x 4 cm) + (3 cm x 3 cm) = $$16cm^2\ +\ 9cm^2=21cm^2$$  

Multiple Choice

Find the area of this figure.

• Area of the figure= Area of rectangle + Area of triangle = (length x breadth) + (½ x base x height ) = (14 cm x 5 cm) + (½ x 8 cm x 5 cm) = $$60cm^2\ +\ 20cm^2=80cm^2$$  

• Area of the figure= Area of rectangle + Area of triangle = (length x breadth) + (½ x base x height ) = (14 cm x 5 cm) + (½ x 6 cm x 5 cm) = $$60cm^2\ +\ 15cm^2\ =\ 75cm^2$$  

• Area of the figure= Area of rectangle + Area of triangle = (length x breadth) + (½ x base x height ) = (6 cm x 5 cm) + (½ x 8 cm x 5 cm) = $$30cm^2\ +\ 20cm^2=50cm^2$$

Multiple Choice

The solid is built using 1-cm cubes.

Volume of Solid C =.......cm³

• Length = 7cm, Breadth = 6cm, Height = 3cm.

  Volume = 126cm³

• Length = 7cm, Breadth = 7cm, Height = 3cm.

  Volume = 147cm³

• Length = 6cm, Breadth = 6cm, Height = 3cm.

  Volume = 108cm³

​Length = 7cm,

Breadth = 6cm,

Height = 3cm.

​

Volume of cuboid

= length x breadth x height

= 7cm x 6cm x 3 cm

= 126cm³

Multiple Choice

Find the volume of the cuboid.

• Volume of cuboid = 26cm x 12 x 18 cm = 5736 cm³

• Volume of cuboid = 26cm x 12 x 18 cm = 5616 cm³

• Volume of cuboid = 26cm x 12 x 18 cm = 5426 cm³

​Length = 26 cm

​Breadth = 12 cm

​Heught = 18 cm

​

Volume of cuboid

= 26cm x 12 x 18 cm

= 5616 cm³
