Question

can anyone help me with this ch perimeter and square and like give me a quick recap and write all the formulas like the circumference of circle and stuff . it would be a great help, thank you. ​

Answer 1

perimeter of rect. 2×length+breadth

area of rect.l×b

area of sq.a=a square

perimeter of sq.4×side

circumfurence of circle is 2 pie r(radius)

Answer 2

Square:

Perimeter of square= 4× Side

Area of square= Side× Side (Side²)

Rectangle:

Perimeter of rectangle= 2× Length+ Breadth (2l+b)

Area of rectangle= Length× Breadth (lb)

Circle:

Circumference of circle= 2× π× Radius (2πr)

Area of circle= π× Radius× Radius (πr²)

Triangle:

Perimeter of triangle= Sum of all sides

Area of triangle= Height× Breadth/ 2(hb/2)

It took me so long to type all these (No, I didn't copy paste it from Google!)
