Question

area and perimeter of triangle Rhombus parallelogram square​

Answer 1

Answer:

Perimeter and Area of the Square:

● Perimeter of square = 4 × S.

● Area of square = S × S.

● Diagonal of square = S√2; (S is the side of square)

Perimeter and Area of the Triangle:

● Perimeter of triangle = (a + b + c); (a, b, c are 3 sides of a triangle)

● Area of triangle = √(s(s - a) (s - b) (s - c)); (s is the semi-perimeter of triangle)

● S = 1/2 (a + b + c)

● Area of triangle = 1/2 × b × h; (b base , h height)

● Area of an equilateral triangle = (a²√3)/4; (a is the side of triangle)

Perimeter and Area of the Parallelogram:

● Perimeter of parallelogram = 2 (sum of adjacent sides)

● Area of parallelogram = base × height

Perimeter and Area of the Rhombus:

● Area of rhombus = base × height

● Area of rhombus = 1/2 × length of one diagonal × length of other diagonal

● Perimeter of rhombus = 4 × side
