Jacob made a banner for a sporting event in the shape of a parallelogram. The area of the banner is 127 1/2 square centimeters. The height of the banner is 4 1/4 centimeters. What is the base of the banner?

Respuesta :

Answer:

30 cm

Step-by-step explanation:

The area of a parallelogram is given by  [tex]A=bh[/tex]

Where

A is the area

b is the base, and

h is the height

Since A and h are given, we plug that in and find the base. Shown below:

[tex]A=bh\\127\frac{1}{2}=b(4\frac{1}{4})\\b=\frac{127\frac{1}{2}}{4\frac{1}{4}}\\b=\frac{\frac{255}{2}}{\frac{17}{4}}\\b=\frac{255}{2}*\frac{4}{17}=30[/tex]

Hence, the base is 30 centimeters
