Answer:
A = 16.5 cm²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A = h (b₁ + b₂ )
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 3, b₁ = 7 , b₂ = 4 , then
A = × 3 × (7 + 4) = 1.5 × 11 = 16.5 cm²
B
Angle is 180
combine like terms
180/9=20
X=20
4x+5x=180
4(20)+5(20)=180

Total amount = 4.95
Per pound of banana = 0.59
Total amount of banana = 0.59 x 3 = 1.77
Remaining amount = 4.95 - 1.77 = 3.18
Cost of per pound of apple = 3.18 ÷ 2 = 1.59
