Question

Please help me with this question I don't know what to do...

Answer 1

Step-by-step explanation:

First let's divide the diagram into triangle and semi-circle .

Triangle's info. ,

Height=48-6.5

=41.5

Base = 13

Area =1/2*13*41.5

=269.75 sq.units

Now the circle info ,

Radius = 13/2 = 6.5

Area = πr^²/2

= 11/7*6.5^²

~66.39 sq.units

Now add the areas ,

269.75 + 66.39

=336.14 sq.units

Answer 2

Answer:

Area of full figure = area of triangle + area of circle

Area of triangle- half x base x height

Area of semicircle - Pi(Radius- half of diameter) WholeSquare

1/2 x 13x(48-13/2) +1/2(Pi(13/2)) ^2

hence proved.

(Final answer- 269.75+ 132.7)

(402.25)
