What is the area of the composite figure?
(611 + 4) cm
(67+ 16) cm?
(121T + 4) cm
(121T + 16) cm?
2 cm

composite figure as it consists of two basic figures. That is, a figure is formed by a rectangle and triangle. The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure

Step-by-step

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.
