Step-by-step explanation:

I drew a diagram on paper but cant here soooo....

but math checks out i think.

Angles AOD and COB are both 36.

Angles AOC and DOB are both 144.

DOB has to be 4 times angle COB, right? if so, then:

144 = 4*36. That checks out. Now to see if all the angles combined are 360.

36 + 36 + 144 + 144 =360. It works!

This is my first answer ever btw so if the formatting and grammar is bad im sorry.

Answer:

pls give brainlist

Step-by-step explanation:

a. $\frac{50 blocks (L)}{9 blocks(W)\\}$ 50 x 9 = 450. A=450

b. I can scale the unit rate of the area given above and largen the area of the map. Ex. $\frac{7}{3}$ = $\frac{21}{6}$ <---(scaled by 2)

Then we can enlarge it however we want so,

$\frac{21}{6}$ = $\frac{42}{12}$ <--(scaled by 2 once more)

If the statement above is true then we can scale times 4.

$\frac{7}{3}$ = $\frac{42}{12}\\$ <---(scaled by 4)

A= $\frac{42}{12\\}$

all i can give u at the moment , if u go on M a t h w a y it can help
