$geometrical \: subject$

Answer 1

Perimeter of rectangle = 2(l+b)
Perimeter of square = 4× side
•perimeter is the sum of all sides so u can calculate it even if u don't know the formula.

Area of rec= lb
Area of square= (side)^2

Volume of cube= (side)^3
volume of cuboid = lbh

Answer 2

perimeter of rectangle =2 (l+b)
area of rectangle =l×b

perimeter of square =4×side
area of square =side×side

volume of cube =6×l×l
volume of cuboid =l×b×h
