A =302 cm^2

Step-by-step explanation:

First find the area of the rectangle

A = l*w  where the length is 27 cm and the width is 13 cm

A = 27*13 =351 cm^2

Now find the area of the square that is unshaded

A = s^2  where s is 7cm

A = 7^2 = 49 cm^2

The total shaded area is  the area of the rectangle minus the area of the square

A = 351-49

A =302 cm^2

302 cm²

Step-by-step explanation:

Shaded area = Rectangle - square

(13 × 27) - 7²

351 - 49

302

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
