Question

A banner in thevshape ofba parallelogram has an area of 25ft square.the height of thr banner is 1 1/4 feet. What is the length of banner, in feet?

Answer 1

20 ft

Explanation

the area of a parallelogram is given by:

$\text{Area}_{paralle\log ram}=base\cdot heigth$

then

Step 1

Let

base=unknow length= x

heingth=1 1/4 feet = 1.25 ft

Area= 25 quare ft

now, replace.

$\begin{gathered} \text{Area}_{paralle\log ram}=base\cdot heigth \\ 25ft^2=x\cdot1.25\text{ ft} \\ 25=1.25x \\ \text{divide both sides by 1.25} \\ \frac{25}{1.25}=\frac{1.25x}{1.25} \\ 20=x \end{gathered}$

therefore, the length of the banner is 20 ft.

I hope this helps you
