Answer:
75 in2
Explanation:
Formulas:
Area of a rectangle/square:
Area of a triangle:
Square:
5*5= 25 in.
Triangles (4):
Multiply by 4.
12.5*4= 50 in.
Add all them up.
25+50= 75
75 in^2
The surface area is the sum of the areas
Area of the square:
A = s^2 = 5^2 =25
Area of one triangle
A = 1/2 bh = 1/2 (5)(5) = 25/2
There are 4 triangles
4* (26)/2 = 50
The sum is 25+50 = 75
