Question

Answer this for me, Please and Thank you! >.<

Find the area of the triangle.

16.5m^2
11.55m^2
23.1m^2
4.85m^2

Answer 1

\[Area = \frac{ 1 }{ 2 } \times \ base \ \times \ height = \frac{ 1 }{ 2 } \times \ 4.2 \times 5.5\]

got it :) ?

Answer 2

I got 23.1

Answer 3

u have to divide it by 2. what will u get then ?

Answer 4

11.55m^2? '.'

Answer 5

yep .... u r correct !

Answer 6

Find the area of the triangle.

874mm^2
42mm^2
437mm^2
21mm^2

Answer 7

apply the same theory i mentioned before

base = 38
height = 23

now
Area= 1/2 x base x height

Answer 8

874

Answer 9

did you divide by 2 ? (or multiply by ½ ?)

Answer 10

u forgot to divide it by 2 again :)

Answer 11

just base * height gives the area of a RECTANGLE

Answer 12

\[Area \ of \ a \ \triangle = \frac{ base \times height }{ 2 }\]

Answer 13

Ok thx

Answer 14

this will be easy to remember and u wont forget the divide by 2 part again ..

Answer 15

The perimeter of the triangle shown is 18 cm. What is the measure of the third side?

Answer 16

perimeter = the length of all the three sides add together
= 6 + 8 + missing side
18 = 6 + 8 + missing side

now u should be able to find the missing side :)

Answer 17

4 cm

Answer 18

yep
