Answer:
0.6625 in²
Step-by-step explanation:
The surface area of this figure will be the area of the base added to area of the triangles
Area of the 4 triangles
Area of a triangle is given by ;
where b is the base length and h is the height of the triangle
<u>Area of 1 triangle</u>
Given base length as 0.25 inches and height is 1.2 inches.
Area of all 4 triangles
- multiply the area of one triangle by 4
- 0.15*4=0.6 in²
<u>Area of the base</u>
The base is a square of length 0.25 inches
Area of a square=length×length
<u>Total surface area</u>
Total surface area= Area of the triangles + Area of the base
