In formula P = 2 (l x b ), make l the subject.
l = 2b - p/2
l = 2 -2b/p
l = p - 2/2b
l= p - 2b/2
Frame a formula for 1/5th of number x is 3 less than 20.
5x = 20 -3
5x = 3 - 20
x/5 = 20 - 3
x/5 = 3 - 20
Given v2 = u2 - 2ft,make t subject of the formula.
t = 2f (u2 - v2)
t = 2f (u2 + v2)
Find the value of f, f = uv/(u +v) if u = 7cm & v = 3 cm

Find the value of 'f' , f=uv/(u +v),if u = 6cm & v = 4cm
-24cm
-2.4cm
-10cm
2.4cm
Given make x as the subject of the formula.
Frame a formula for " perimeter (p) is twice the sum of its length (l) and breadth (b)
P = 2l + b
P = l + 2b
P = (l + b)2
P = 2(l + b)
Find the value of 'f',f =uv/(u + v), if u = 10 cm & v = 5cm
10cm
3.3cm
