Find the area of each figure in Exercises 1924 Where necessa

Find the area of each figure in Exercises 19-24. Where necessary express answers in terms of pi and then round to the nearest tenth.

Solution

21 The figure has one triangle with sides - 13m ,13m, 24m (base) and a rectangle with sides 10m x 24m

Now triangle 13m , 13m , and base 24m has height = 5m

Area of triangle = (1/2)(base*height) = (1/2)(24)(5) = 60m^2

Area of rectangle = 10 x 24 = 240m^2

S, total area of figure = 60 +240 = 300 m^2
