topic plzz i am waiting.

(a+b)^2 = a sq +b sq +2ab
(a-b )sq = asq + b sq -2ab
in fraction if 1 value is not given then you can do cross multiply
sum of two side of triangle is allways greater then 3rd side
hypoteneous sq = perpendicular sq + base sq.
parameters
square = 4a
rectangle = 2(l+b)
circle = 2πr.
semicircle =πr
AREA
Square = a ×a
rectangle = l×b
circle = π r sq
to find any % = any given valu ÷ total × 100
