Question

Calculate the Area of each of the following Figures:​

Answer 1

Answer:

2.2.1 Area = 12.6 cm²

2.2.2 Area = 12 cm²

Step-by-step explanation:

2.2.1:

The radius of the big circle is half the length of the square = 2.5 cm

The radius of the small circle is half of 3 cm = 1.5 cm

The area of the shaded portion is = Area of big circle - Area of small circle

π × 2.5²-π × 1.5² = 12.6 cm²

2.2.2

To find length BD (the height of the parallelogram) we need to use the Pythagorean theorem:

BD = √(5²-3²) = 4

Area = base x height = 3x4 = 12 cm²
