Answer:
21 in²
Step-by-step explanation:
The net consists of a square and 4 triangles. The relevant dimensions of each are given, so the appropriate area formulas can be used.
Area of one triangle:
A = 1/2bh
A = 1/2(3 in)(2 in) = 3 in²
Area of the square:
A = s²
A = (3 in)² = 9 in²
__
Total net area (surface area of the pyramid):
square area + 4 × triangle area
9 in² + 4 × 3 in² = 21 in² . . . . surface area

Step-by-step explanation:
i guess 4th one
She bought 11 shirts and 4 pants
Let x= pants
Let y= shirts
x+y=15
x+7=y
x=y-7
(y-7)+y=15
2y=22
y=11
x+y=15
11+x=15
x=4
Therefore, Elaine bought 11 shirts and 4 pants
