The answer should be 95in^2
Explanation:
You’re essentially just finding the area of all the shapes on the triangle and adding them together.
Area of a triangle = 1/2•b•h
Area of a square = l•w or just s2
The area of the triangles given what we have in the diagram can be found with
1/2•5•7 = 17.5
There are 4 triangles so you multiply 17.5 by 4 which gives 70
The base of the triangle (the square) = 25
70+25=95
21/7 = 3 so then, 105/7 = x which is 15
I’m hoping this helps (but hopefully now you can give the brainliest to the person above)
I’m not very familiar with the square roots method but I believe you try and isolate the term that is squared.
