John is building a fence around his home. Currently his fence measures 14 feet on each side but he wants to increase only the width of his fence by x feet to have a rectangular fence that has an area of 280 square feet. Write an equation that can be used to find x then solve your equation

The value of x is 6 feet.

Step-by-step explanation:

Area of rectangle = lengthwidth

280 = (14) (14+x)

280/14 =  14+x

20 = 14+x

x = 20-14

x = 6 feet

The width of the rectangular fence is (14+x) = 20 feet.

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.
