A rectangle has perimeter 32cm. The rectangle is three times as long as it is wide. What is the area of the rectangle |

Answer» Answer: Step-by-step explanation: I will call the width W so the LENGTH L = 3W – 4 Now doesn’t that feel good? The total perimeter is… 3W – 4 + 3W – 4 + W + W = 32 Combine terms……… 8W – 8 = 32 Add 8 to both sides…….. 8W = 40 Divide both sides by 8…… W = 5 Solution: The width is 5cm and the length is 11CM |
