Question

Chapter 10.3, Problem 27E

To determine

To calculatethe area of polygon.

Expert Solution & Answer

Answer to Problem 27E

20 square units.

Explanation of Solution

Given Information: (2,3),(2,−4), (−2,−3),(−2,0)

Formula Used:Distance between (x1,y1) and (x2,y2) = (x2−x1)2+(y2−y1)2 , Height = |x2−x1| , Area of Trapezoid: 12×Sum of parallel bases×Height .

Calculation:

Holt Mcdougal Larson Pre-algebra: Student Edition 2012, Chapter 10.3, Problem 27E

According to graph, it indicates it’s a Trapezoid.

Distance between (x1,y1) and (x2,y2) = (x2−x1)2+(y2−y1)2

Distance between (2,3) and (2,−4) = (2−2)2+(−4−3)2

Distance between (2,3) and (2,−4) = 7 units

Distance between (x1,y1) and (x2,y2) = (x2−x1)2+(y2−y1)2

Distance between (−2,−3) and (−2,0) = (−2+2)2+(0+3)2

Distance between (−2,−3) and (−2,0) = 3 units

Height = |x2−x1|

Height = |−2−2|

Height = |−4|=4 units

Area of Trapezoid: 12×Sum of parallel bases×Height

Now, Base1 = 7, Base2 = 3 and Height = 4.

Area of Trapezoid: 12×(7+3)×4 square units

Area of Trapezoid: 10×2 square units

Area of Trapezoid: 20 square units
