Step-by-step explanation:

The question has lots of missing details. See the comment section for complete question

Solving (a):

Given

Shape: Quadrilateral

Sides: Consecutive

Let one of the sides be x. The other sides will be x + 1, x + 2 and x + 3.

So, the perimeter is:

This gives:

Collect Like Terms

Divide both sides by 4

So, the sides are: 38.5, 39.5, 40.5 and 41.5

Solving (b):

Given

Presently:

Five years ago: --- (Missing from the question)

Required: Determine their present ages

Substitute for Inzo in the second equation

Multiply both sides by 3

Collect Like Terms

Divide both sides by 2

Substitute 10 for Miz in

So presently, Inzo is 15 years old and Miz is 10 years old

Solving (3):

Given

Express Train:

Local Train:

Required: Determine the distance between A and B

Distance is calculated as:

For the express train:

For the local train

Distance between both stations are equal; So,

Collect Like Terms

Divide by 55

Substitute 36.82 for t in

Solving (4):

Let the even numbers be: n and n + 2.

Sum greater than 24:

Sum less than 60:

So, we have:

Collect Like Terms

Collect Like Terms

Divide by 2

So, we have:

and

So, possible pairs are: (12, 14), (16, 18) and (20, 24)

Solving (5):

Given

Required: Find the possible lengths

Let the length be L.

Perimeter is calculated as:

So, we have:

Divide through by 4

Hence, length is less than 38m (e.g. 37m)

i think it would be 42cm
