Answer 12

the area of a parallelogram is baseXheight so in this problem your base is 2cm and the height is 2.9cm when you multiple them you get 5.8 cm squared.

Answer 13

just remember that a parallelograms area is the same as a triangles area

Answer 14

ok ok i get it......

Answer 15

remembering the equations is the hardest part and not over thinking the problems...

Answer 16

yes ok.

Answer 17

the area of a triangle is 1/2(base)(height)
in this problem the base and height multiple to 32 and when you divide that in half you get an area of 16 cm squared

Answer 18

thx

Answer 19

Area of the whole figure - the area of the inscribed figure

Answer 20

26.8 yards squared

Answer 21

i mean so 1.6*2

Answer 22

and ok @slyoungdale

Answer 23

The area of the whole is 30 then you subtract this by 3.2 (1.6*2). What do you get?

Answer 24

first find the area of the unshaded portion and then subtract that area from the area of the larger section.

Answer 25

128?

Answer 32

Correct

Answer 33

oh srry i had my mouse on this type box. i am not really typing

Answer 34

Don't worry. Happens to me often.

Answer 35

i cant quite find this out


i need help to find the height of this question. The area of a triangle is 56.4 square inches and the base is 12 inches. What is the height of this triangle?

Answer 36

Since we know that the area of the triangles formula is 1/2(b*h), we already know that the area is 56.4. But this number is half of another number. To get this you want to multiply 56.4 by 2 and then divide by 12 because 12 times another number equals to 56.4*2.

Answer 37

112.8

Answer 38

Give me a sec

Answer 39

112.8 is when you multiply by 56.4. You didn't divide by 12.
