Step-by-step explanation:

The rear window of DeMarcus's car is in the shape of a trapezoid. The bottom is 50 inches across and the top is 45 inches across. The window has a height of 24 inches. What is the area of the window?

Area of a Trapezoid

= 1/2(b1 + b2)h

b1 =

b2 =

h =

Hence, 1/2 (50 + 45) × 24

= 1/2 × 95 × 24

= 1140 Square inches

Principal

Step-by-step explanation:

Since, the amount in the simple interest is,

Where, P is the principal amount,

r is the annual rate,

t is the time ( in years ),

Here, r = 3.75 %, t = 6 years,

Thus, By the above explanation,

It is clear that, we need the value of P, that is, principal to find the amount.
