Answer 1

Answer:

Step-by-step explanation:

Question 2:

//See the attached figure for explanation.

The figure can be broken down into 3 rectangles:

Rectangle 1: length = 8cm and breadth = 3

Area = 8 * 3 = 24 Sq.cm

Rectangle 2: Length = 8 cm, breadth = 4 cm.

Area = 8 * 4 = 32 Sq.cm.

Rectangle 3: Length = 16 - 8 = 8cm, breadth = 4 + 3 + 3 = 10 cm.

Area = 8 * 10 = 80 Sq. cm.

Total = 24 + 32 + 80 = 136 sq.cm.

Question 3:

// see the attached figure

The figure can be broken down into 3 rectangles:

Rectangle 1: length = 7cm and breadth = 6 cm

Area = 7 * 6 = 42 Sq.cm

Rectangle 2: Length = 7 cm, breadth = 3 cm.

Area = 7 * 3 = 21 Sq.cm.

Rectangle 3: Length = 7 cm, breadth = 6 cm.

Area = 7 * 6 = 42 Sq. cm.

Total = 42 + 21 + 42 = 105 sq.cm.
