The area of an isosceles right triangle is 18 cm2.What is the length of the hypotenuse of the triangle?

  1. 6 cm
  2. 62 cm
  3. 182 cm
  4. 183 cm
  5. 362 cm

Answer(s): B

Explanation:

The area of a triangle is equal to where b is the base of the triangle and h is the height of the


triangle. The base and height of an isosceles right triangle are equal in length. Therefore,



If which of the following could be true?

  1. Option A
  2. Option B
  3. Option C
  4. Option D
  5. Option E

Answer(s): A

Explanation:

If a = 4, x could be less than
A. For example, x could be


Although x<a is not true for all values of x, it is true for some values of x.



The length of a rectangle is one greater than three times its width. If the perimeter of the rectangle is 26 feet, what is the area of the rectangle?

  1. 13 ft2
  2. 24 ft2
  3. 30 ft2
  4. 78 ft2
  5. 100 ft2

Answer(s): C

Explanation:

The perimeter of a rectangle is equal to2l+2w, where l is the length of the rectangle and w is the width of the rectangle. If the length is one greater than three times the width, then set the width equal to x and set the length equal to 3x+1:


The width of the rectangle is3ftand the length of the rectangle is10ft. The area of a rectangle is equal tolw; (10 ft)(3 ft) = 30ft2.



  1. Option A
  2. Option B
  3. Option C
  4. Option D
  5. Option E

Answer(s): A

Explanation:

The measure of an exterior angle of a triangle is equal to the sum of the two interior angles of the triangle to which the exterior angle is NOT supplementary. Angle i is supplementary to angle g, so the sum of the interior angles e and f is equal to the measure of angle
