The combined area of a square and a rectangle is 249 square centimeters. the width of the rectangle is 3 centimeters more than the length of a side of the square, and the length of the rectangle is 2 centimeters more than its width. find the dimensions of the square and the rectangle.

answer: the answer is 35%

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.
