Question

Q4. The first side of a triangle is Y cm long.
The second side is twice as long as the first.
The third side is 5cm longer than the second side.
a) The perimeter of triangle is 1m.
Write an equation to show this. (2)
Second side=
Third side =
Equation =
b) Solve the equation (1)
c) Find the length of the longest side of the triangle. (1)


answer correct and who knows urgent please who knows then only answer

Answer 1

Answer:

a)First Side = Y = 19cm

Second side = 2Y = 38cm

Third Side = 2Y+5 = 43cm

Equation = (Y)+(2Y)+(2Y+5)

b)  (Y)+(2Y)+(2Y+5)=100cm

      5Y+5=100cm

      5Y = 100-5

      5Y = 95

      Y = 19cm

c)  Longest Side of Triangle = 43 cm
