A rectangle is three times as long as it is wide. It’s perimeter is 36 units. Find the length of each side

Step-by-step explanation:

Let us say that the width is x

So this means that the legth is 3 times the width or 3x

Perimeter means to add up all the sides in the shape

So form an equation : 2(x)+2(3x)=36

And once you solve it you get x=36/8.

The width is 3(36/8) which is 13.5

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
