Question

A piece of wire 80 cm long is cut into two parts. Each part is made into square.
Let x represens the side length of the first square and y represents the side length of the second square.
(a) Express y in term of x.

Answer 1

Step-by-step explanation:

total length of wire is 80cm

The wire is cut into two parts, and of these two parts square is made.

the side length of first square is x cm

the side length of second square is y cm.

According to the question,

perimeter of first square is 4x cm

perimeter of second square is 4y cm.

total length of wire = perimeter of first square+ second square

80cm = 4x +4y

80-4x= 4 y

therefore, y= 20-2x
