If a rectangle has a perimeter of 36 feet, and it is 4 feet wide, what is its area?
A. 56 square feet B. 128 square feet C. 112 square feet D. 16 square feet |
To find area, (A=LW). To determine the length, subtract two times the width from the perimeter: 36 - 2(4) = 36 - 8 = 28. Then divide the remainder by 2 to determine the length of one side: 28 ÷ 2 = 14. Then multiply length times width to determine the area : 14 × 4= 56.

If I = prt, and p = $1,000, r= 7%, and t = 1, what does I equal?
A. $35 B. $1,000 C. $700 D. $70 |
Solve for I. I = ($1,000)(7%)(1) or I = ($1,000)(0.07)(1) = 70.
