The length of a triangle is 1 1/8 cm longer than the width. The perimeter is 13 1/4 cm. What are the width and length of this triangle?

See explanation

Step-by-step explanation:

I think your question should be a rectangle and not a triangle. A triangle has 3 sides and not 2 sides. In order to solve the question, I'm assuming that you wanted to write rectangle.

Note that the perimeter of a rectangle:.= 2(length + breadth)

Let the width be x

Since the length is 1 1/8 cm longer than the width, therefore, the length is 1 1/8 + x.

Therefore, perimeter = 2(1 1/8 + x + x) = 13 1/4

2(1 1/8 + 2x) = 13 1/4

2 2/8 + 4x = 13 1/4

2 1/4 + 4x = 13 1/4

4x = 13 1/4 - 2 1/4

4x = 11

x = 11/4

x = 2 3/4

Therefore, the width is 2 3/4cm

Length = 2 3/4 + 1 1/8

= 2 6/8 + 1 1/8

= 3 7/8cm

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
