Find the Area. Please help! (Picture included)

Area of the figure = 126 cm²

Solution:

The given figure is splitted into two shape.

One is rectangle and the other is triangle.

Length of the rectangle = 9 cm

Width of the rectangle = 12 cm

Area of the rectangle = length × width

                                    = 9 × 12

Area of the rectangle = 108 cm²

Base of the triangle = 12 – 3 – 3 = 6 cm

Height of the triangle = 15 – 9 = 6 cm

Area of the triangle =

Area of the triangle = 18 cm²

Area of the figure = Area of the rectangle + Area of the triangle

                              = 108 cm² + 18 cm²

                              = 126 cm²

Area of the figure = 126 cm²

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
