What is the area of this composite figure A) 180.48 cm

B) 260.48 cm

C) 280.96 cm

D) 360.96 cm

Area of Triangle = 1/2 bh

                    A = 1/2 (16 cm x 10 cm)

                   A = 160 cm2/2

                    A = 80 square cm

Area of Circle = d2/4

                  A = 3.14 x (16 cm)2 / 4

                  A = 3.14 x 256 cm2 / 4

                 A = 803.84 cm2 / 4

                 A = 200.96 cm2

        Area of Half Circle = 200.96 cm2 / 2

                 A = 100.48

Composite Figure = Area of Triangle + Area of half Circle

Area of Composite Figure = 80 cm2 + 100.48 cm2

Area of Composite Figure = 180.48 cm2

the answer is true.

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
