Find the area of the compound shape. use 3.14 for pi. 1. 26.1cm square 2
2. 125.1cm square 2
3. 68.5cm square 2
4. 28.3cm square 2

1. 26.1 cm²

Step-by-step explanation:

For area of semi circle

diameter = 6cm

radius = 6/2 = 3cm

Area of semi circle = 1/2 x pi x r²

= 1/2 x 3.14 x 3²

= 1.57 x 9

= 14.13 cm²

For area of rectangle,

length = 6cm

breadth = 2cm

Area = length x breadth

= 6 x 2

= 12cm²

Area of compound shape = 14.13 + 12

= 26.13 cm²

Step-by-step explanation:

Ok, this problem is on construction in mathematics.

also, see attached a rough sketch of the two constructions.

The similarities, as can be seen, is that for both constructions, we need to two major points to obtain a bisector, for the line segment the major points are (A and B) and for the angle segment the points are(P and Q)

The difference between the two construction is that the line segment needs basically two bisectors to equally divide the line located at (O and P), while the angle segment needs just one bisector at (O) to bisect the angle.
