Question

The perimeter of a rectangle poster is 3 1/12 feet. Given that the width of the poster is 2/3 foot, find the area of the poster

Answer 1

Area=l×b = 3 1/12 × 2/3 = 37/12 × 2/3 =37/18 is the answer

Answer 2

Perimeter = 2( Length + Width)

Given that Perimeter = 3 1/12 feet and Width = 2/3 foot, plug the values into the formula to find the length:

3 1/12 = 2( Length + 2/3)

3 1/12 = 2Length + 4/3

2 Length = 3 1/12 - 4/3

2 Length = 7/4

Length = 7/4 ÷ 2

Length = 7/4 x 1/2

Length = 7/8

Now that we know the length is 7/8 and the width is 2/3, find the area:

Area = Length x Width

Area = (7/8)(2/3) = 7/12

Answer: Area = 7/12 ft²
