The area of the trapezoid is 43.5 inches²
Step-by-step explanation:
The formula of the area of a trapezoid is 
, where:
and 
are the two parallel bases- h is its height
∵ = 
feet
∵ = 14 inches
∵ h = 3 inches
- Change the length of from feet to inches
∵ 1 foot = 12 inches
∴ feet = × 12 = 15 inches
∴ = 15 inches
Substitute the values of , and h in the
formula of the area
∴ 
∴ A = 43.5 inches²
The area of the trapezoid is 43.5 inches²

Answer:
See below in bold.
Step-by-step explanation:
The triangular piece of cloth is a right triangle because 41^2 = 40^2 + 9^2 (By the Pythagoras theorem).
So the area of one piece = 1/2 * 9 * 40 cm^2.
The total amount of cloth required for one umbrella = 10 * 1/2 * 9 * 40
= 1800 cm^2.
The total cost = 1800 * 0.25 = Rs 450.
Answer:
C
Step-by-step explanation:
40x + 3
5(a - 2b) - 3(a - 2b) |use distributive property: a(b - c) = ab - ac
= 5a - 10b - 3a + 6b
= (5a - 3a) + (-10b + 6b)
= 2a - 4b
