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)
If A = π r2 find A when r = 14 cm and π = 22/7 ?
516 cm2
616 cm2
716 cm2
916 cm2
Given make v the subject of the formula.
Find the value of f, f = uv/(u +v) if u = 7cm & v = 3 cm
2.1cm
21cm
7 cm

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
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
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 = 12cm & v = 4cm

A number decreased by 15 is 35.Derive the formula.
x - 15 = 35
15 - x = 35
35 - 15 = x
x -35 = 15
Find the value of 'f',f =uv/(u + v), if u = 10 cm & v = 5cm
