Find the area of the figure.

5.5in^2

Step-by-step explanation:

1 x 1 = 1

3 x 3 = 9

9/2 = 4.5

4.5 + 1 = 5.5

Area = 5.5 inches square

Step-by-step explanation:

First, find the small square's area: 1 * 1 = 1 in square

Next, find the big triangle's area: 3 * 3 / 2 = 4.5 in square

Add the areas together:

1 + 4.5 = 5.5 in square

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
