Below are the dimensions of an assortment of rectangles. which rectangle has dimensions that are similar to a rectangle that has a dimension 2 times 5? assume that all the units are identical.
5 times 8 6 times 9 4 times 10 1 times 10 8 times 20 10 times 4

Side of the original square. x2 x. Square has all sides the same length x ... 2. Our Solution. Example 3. The length of a rectangle is 4 ft greater than the width. If each dimension is ... (x+ 3)(x+ 7) =x(x+ 4) +33 Set up equation, length times width is area  5) 6 x 10. 6) 20 ft x 35 ft. 7) 6” x 6”. 8) 6 yd x 7 yd. 9) 4 ft x 12 ft. 10) 1.54 in.

Let the side of the square = x

So, the altitude of the triangle = x
and it's base = x+3

2 (area of triangle) - 18 = area of the square

area of the triangle = (1/2)height× base
and
area of the square = side^2

{ (2)(1/2)(x)(x+3)} -18 = x^2
x^2 + 3 x -18 = x^2
3x -18 =0
3x = 18
x = 6

so, the length of one side of the square = 6 units = altitude of the triangle
and the base of the triangle = 6+ 3 = 9cm.
