Question

The total area of the compound structure is 80 cm2. The Diameter FG = AB.
Find: -

a) the length of the side AG?


b) the total area of ABCDEFG. If the radius = 10 cm? (AB = FG = 10 cm)​

Answer 1

Answer:

a) 49/5. b)101

Step-by-step explanation:

a) since ABFG is a rectangle

area is length×breadth

5×length=49

length(AG)=49/5

b). AB=FG=10= length

area of ABFG is 10×49/5

98

therefore total area of ABCDEFG is

98+3

101
