Find the Area of the figure below, composed of parallelogram and two semicircles.
Makovka662 [10]

Answer:

622.13 square units

Step-by-step explanation:

Area of the composite figure = area of parallelogram + area of circle

Note: 2 semicircles = 1 full circle

Area of the figure = a*h + πr²

Where,

a = 22

h = 11

r = ½ of 20 = 10

Plug in the value into the equation

Area = 22*11 + π*11²

Area = 242 + π*121

Area = 622.13271108 ≈ 622.13 square units (nearest tenth)

hodyreva [135]

The height that Trey jumped is; 13/3 ft

<h3>How to simplify Algebra Word Problems?</h3>

We are given that;

Height that trey jumped = 6¹/₂ ft

Now, Conner jumped = ²/₃ ft

Now, we know that if Conner jumped ²/₃ ft as far as trey, then it means that;

Height that Trey jumped = ²/₃ * 6¹/₂

Height that Trey jumped = ²/₃ * ¹³/₂ = 13/3 ft
