Answer 1

Answer:

TRIANGLE:-

Thus, the area of a triangle is half the product of its base and height. The area A of an equilateral triangle of side length s cm can be calculated using the formula A = √3⁄4 s². The value of √3 is about 1.73. Thus, the approximate area becomes, A = 0.4325 s².

CIRCLE:-

In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.14159.

PARALLELOGRAM :-

Area of Parallelogram (A) = a * b sin (x)

Where a and b are the length of parallel sides, and x is the angle between two sides.

SEMI CIRCLE:-

Using the formula: Area of semicircle=πr22 Area of semicircle = π r 2 2 , we will find the area.
