For a particular rectangular region, the ratio of its width to its length is 5 to 12. If the length of the region decreases by 9 units, by how many units does the width change to maintain the original ratio?It must decrease by 9 units.eliminateIt must increase by 9 units.eliminateIt must decrease by 3.75 units.eliminateIt must increase by 3.75 units.

A rectangle is reduced by a scale factor of One-fourth. A large rectangle has a length of 16 and width of 12. A smaller rectangle has length of 4 and width of 3. Which choices show the ratio of the area of the smaller rectangle to the area of the larger rectangle? Select three options. StartFraction 4 over 16 EndFraction (StartFraction 4 over 16 EndFraction) squared StartFraction 12 over 192 EndFraction StartFraction 4 squared over 12 squared EndFraction (StartFraction 3 over 12 EndFraction squared

The rectangle below has been reduced by a scale of StartFraction 1 over 10 EndFraction. A rectangle has a length of 15 and width of 12. [Not drawn to scale] What is the area of the reduced rectangle? 0.18 square units 1.8 square units 18 square units 180 square units

For a given set of rectangles, the length is inversely proportional to the width. In one of these rectangles, the length is 5 and the width is 21. For this set of rectangles, calculate the width of a rectangle whose length is 35.

The breadth and length of a rectangle are in the ratio 2 : 3. Also, if numerical values of the breadth, length and area of the rectangle are in a continued proportion, then find the area of the rectangle.

If the width of a rectangle is increased by 25% while the length remains constant, the resulting area is what percentage of the original area ?25%75%125%Cannot be determined by the information givenIncrease by 40%
