How to find perimeter of quadrilateral? Chapter mensuration
Answers
Answer:
To do sum of all side for finding the perimeter of quadrilateral
Answer: We have learnt that for a closed plane figure, the perimeter is the distance around its boundary and its area is the region covered by it. We found the area and perimeter of various plane figures such as triangles, rectangles, circles etc. We have also learnt to find the area of pathways or borders in rectangular shapes.
Step-by-step explanation:
Areas of some standard shapes
Shapes Area Perimeter
Rectangle: product of two sides=ab 2(a+b)
Square: (side)²a² 4a
Triangle: 12 × base × height = 12× b × h Sum of all three sides
Parallelogram: base × perpendicular height = b × h Sum of all four sides
Circle: π × (radius)2 = π × b2 2 × π × radius = 2πb
