Measurements math formula

Secondary school education measurements study for measurements math formula and example

Triangle of Area    = 1/2 land ×h

Right angle of area  = land×bas×h

Equilateral triangle of area  = √3/4a✓

Acute angle of Area = √s(s-a)(a-b)(s-c)

S= half triangle a+b+c/2

Parallelogram of area= (land×h)

Parallelogram of perimeter= 2(length +widths)
Expand of area =(length+widths)

Expand of perimeter = √a✓+b✓

Square if area (1 side)=a✓

Square of area = 4×1 side

Square of perimeter= √a✓+b✓= √2a✓= √2a

Rhombus of area= 1/2× multiple of angle

Rhamnus of perimeter=4×length of one side

Aerial of area =1/2×(added of parallelogram)×distance
Solids body =  length×width×h

Solid body of area = a3

Expand of solids bidy=6a✓

Circle of area= πr✓

Circumstance=2rd

Circle of proportion = 22/7=3.14

Sectorial of circle= °/360πr✓

(a+b)✓=a✓+2ab+b✓=(a+b)✓-4ab
(a-b)✓=a✓-2ab-b✓=(a+b)✓+4ab
a✓-b✓=(a+b) (a-b)
a✓+b✓=(a+b)✓-2ab=(a-b)✓+2ab
            =1/2{(a+b)✓+(a-b)✓}
ab      =(a+b/2)✓-(a-b/2)✓
4ab    =(a+b)✓-(a-b)✓
(a+b+c)✓=(a✓+b✓+c✓+2ab+2bc+2ca
(a✓+b✓+c✓)=(a+b+c)✓-2(ab+bc+ca)
2(ab+bc+ca)=(a+b+c)✓-(a✓+b✓+c✓)
(a+b)3=a3+3a✓b+3ab✓+b3
(a-b)3=a3-3a✓b+3ab✓-b3
a3+b3=(a+b)3-3ab(a+b)=(a+b)(a+ab+b✓)
a3-b3=(a-b)3+3ab(a-b)=(a-ab+b✓)

Interest Math formula

Secondary school education intereste math formula

P        =                    p×rat×time/100

P      =                   100×ti/time×rate
Pi  =            100×pi/(time×r)+100
R          =           100×pi/p×time
Time         =          100×ti/p×rate
Cycle      =        p(1+rate/100) year's
We are by heart several math formula . It's very easy way so okay viewer's.
