Question

write the area and perimeter of triangle, rectangle, circle, rhampus ,tarpezium , parallelogram​

Answer 1

Answer:

$area \: of \: triangle \: = \frac{1}{2} b \times h$

where,

• b is the base
• b is the base b is the height

$perimeter \: of \: triangle \: = s1 + s2 + s3$

where,

• S1,S2 and S3 are the three sides respectively

$area \: of \: rectangle = l \times b$

where,

• l is the length
• b is the breadth

$perimeter \: of \: rectangle \: = 2(l + b)$

$area \: of \: circle = \pi {r}^{2}$

where,

• π is a constant with value 22/7 or 3.14 ( approx.)
• π is a constant with value 22/7 or 3.14 ( approx.)r is the radius of the circle

$perimeter \: or \: \: circumference \: of \: circle = 2\pi \times r$

$area \: of \: rhombus = \frac{ \frac{1}{2} \times d1 \times d2}{2}$

where,

• d1 and d2 are the diagonals

$perimeter \: of \: rhombus = 4a$

where,

• a is the side

$area \: of \: trapezium \: = \frac{1}{2} h \times (b1 + b2)$

where,

• h is the height
• b1 and b2 are the parallel sides

$perimeter \: of \: trapezium \: = s1 + s2 + s3 + s4$

where,

• s1, s2, s3, and s4 are the sides

$area \: of \: a \: parrallelogram = b \times h$

where,

• b is the breadth
• b is the breadthh is the height

$perimeter \: of \: parrallelogram = 2(l + w)$

where,

• w is the width
• l is the length
