On a boat, a cabin's window is in the shape of an isosceles trapezoid, as shown below. What is the area of the window? An isosceles trapezoid with top side 10 inches long and a longer bottom side. The height is 15 inches. The base of the triangle formed from the height on the right is labeled 3 inches.

a
140 square inches
b
150 square inches
c
195 square inches
d
390 square inches

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
