Answer:
Step-by-step explanation:
a) Area of one parallelogram shaped piece = base * height
= 3*4 = 12 square inch
Area of 15 parallelogram shaped piece = 12*15 = 180 square inches
b) Area of wall to be painted = base*height/2

= 104 ft²
Two feet is 66.67% of a yard.
This is because a yard is three feet, and two feet is two-thirds of three feet.
Two-thirds of 100 is 66.67, making two feet 66.67% of a yard.
I hope this helps.
