Question

Daisy is making an abstract painting with two triangles. The dimensions of the painting are shown below:

The total area of the two triangles is
square inches.

Answer 1

ok, we have to find the area of each triangle individually, and then sup it all up together

this is the formula we will be using

\[ \color{dodgerblue}{\triangle}\color{lightskyblue}{A} \color{lightskyblue}{\scriptsize\text{rea}} =\frac{\color{chocolate}{b} \times \color{teal}{h}} {2} \]

Answer 2

these will be our triangles

Answer 3

for our first one,

\[ \color{chocolate}{b} = 12 in \]

\[ \color{teal}{h} = 10 in \]

Answer 4

60

Answer 5

yes!

what about our second one?

Answer 6

b=10

h=8

Answer 7

ok, so what will its area be?

Answer 8

40

Answer 9

perfect!
\[ \color{dodgerblue}{\triangle 1}\color{lightskyblue}{A} \color{lightskyblue}{\scriptsize\text{rea}} + \color{dodgerblue}{\triangle 2}\color{lightskyblue}{A} \color{lightskyblue}{\scriptsize\text{rea}} = \text{our answer} \]

Answer 10

100

Answer 11

there you go!
