The polygons are similar the area of one polygon is given find the area of the other polygon ​

90

Step-by-step explanation:

So to find the area of the triangle you do basexheight/2 I had the base which was 4 so I had to figure out what times 4 divided by 2 equals 10? So I knew 20/2 = 10 so then I made it easier for myself I would just have to do 4x?=20, that's 5! So then 4x5=20/2= 10 the area for triangle one, so then I had to find the ratio 4/12= 0.3 which would mean I would have to multiply 5x3 so then I got 15, then I plugged it in the problem 12x15=180/2= 90!

answer: i wpould go with c

step-by-step explanation:

twenty-six miles over two gallons because the proportion for the original 13 miles to one gallon would be written 13/1 and, doing the same thing to the top and bottom, i multiplied by 2 and got 26/2
