Need fast answer im ! you want to build a fence in your back yard for a rectangular garden. the garden will be up against your house, so you only need three sides to your fence. the long side (the length) will be along the wall. (feel free to draw a diagram on paper like we did for the review problem.) if you want the length to be twice the width, and if you have 44 feet of fence, what will the length be? your answer will be in feet, but just type the number. do not type the word "feet". do not type "l=". hint: write equations for the total length of fence around the garden and for the length in terms of the width. plug in the information that you know and solve your equation. check yourself when done by rereading the problem and see if your answer works.

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
