Question

PLEASE HELP

Find the area of these figures.

Answer 1

Answer:

in first figure total area of rectangle is is l into b so 13 x 8 =104m^2

area of the triangular figure=1/2 *l*b

so area of triangle=1/2*6*5

= 15m^2

so area of the figure is is equals to total area of rectangle substract by area of triangle=84m^2

in the second figure

in the same way total area of triangle =1/2*l*b

=1/2*9*7

=31.5inch

and area of the cut triangle

=1/2*2*4

=4inch

so area of the figure is total area of triangle abstract by area of the cut triangle=27.5inch

in the third figure

first of all draw a line to make a diameter of a semi circle so diameter of the semi circle is 3m

first of all we find out the area of semicircle and then find out the area of total square then subtract semi circle from the total square then we find the the area of the figure

area of the semicircle=πr^2

=π×3×3

=28.28ft

off the square=L×L

=6*6

12ft

so we subtract a semicircle from a square equals to16.2ft
