$A2=4,P1=5$

$S1=1,P2=7$

$A3=8,P3=8$

$S2=2,P4=10$ i need help calculating A$1$ and A$4$

Hiw $**1$ Preunustis

Given: $A2=5i{v}^2$

$P_1=15$ psi

$P_2=10$

$P_3=20$

$P_4=25$

$P_5=20$

$P_6=15$ psi

$A3=()2$

$A_4=13i{n}^2$

Stem $2(S2)=()2$

Galculate: $F1,F2,F3,F4,F_{\text{R}\text{i}\text{G}\text{M}\text{I}},F_{\text{L}\text{e}\text{f}\text{t}},F_{\text{S}\text{t}\text{a}\text{t}}$ & $F_{\text{F}\text{i}\text{N}\text{R}\text{L}}$at the bottom of the photo it says Calulate F$1$ and F$2$ and F$3$ and F$4,$ F right $,$ F left F Start F final
