A.
If you roll up the quarter circle and cap the open end with the smaller circle, the resulting shape should be a cone.
120% is the same as 120/100
Divide 120 with 100
120/100 = 1.2
1.2 > 1 ∴ 120% is 'more than' 1

Answer:
because the length is 4 feet more than the width

because the base has an area of 21 square feet
=> x(x + 4) = 21
<=> x² + 4x = 21
