Question

Define the following figures and also give the formula for finding the area and perimeter of the figure
1. Square
2. Rectangle
3. Right angled triangle
4. Parallelogram
5. Circle​

Answer 1

Answer:

Sqaure- side x side , 4 side

rec - lb, 2(l+b)

right angled triangle - root 3/4 x side² , sum of all sides

parallelogram - 1/2 bxh, 2(l+b)

circle - pie r² , 2 pie r x h

Answer 2

Step-by-step explanation:

SQUARE-- A quadrilateral whose all angles are equal to 90 degree and all the sides are equal are called a square.

AREA OF SQUARE= ( SIDE)^2

PERIMETER OF SQUARE =4×SIDE

RECTANGLE-- A quadrilateral whose all angles are equal to 90 degree and opposite sides are equal are called rectangle.

AREA OF RECTANGLE= LENGHT×BREATH

PERIMETER OF RECTANGLE= 2×(L×B)

RIGHT ANGLED TRIANGLE-- A tiangle whose one angle is of 90 degree is called a right angled triangle.

PARAIIEIOGRAM-- A quadrilateral whose opposite sides are equal are called a parallelogram.

CIRCLE-- The collection of all those points in a plane which are at fixed distance from a fixed point is called a circle, where the fixed point is called centre of the circle and the fixed distance is called radius of the circle.
