Answer:
The area of the rectangle is 2820 square inches. The length is 60 inches. The width is 47 inches.
Step-by-step explanation:
Since we know the equation to find the width, we have to set them both to the perimeter of 90 inches. We will use the variable <em>x</em> to represent the length.
<em>x + x - 30 = 90</em>
<em>2x - 30 = 90</em>
<em />
You would then subtract 30 from both sides.
<em>2x = 60</em>
Divide by 2 on both sides, finding that the length (x) is 30 inches.
<em> x = 30 inches.</em>
<em></em>
Then, subtract 13 inches from the length to find your width.
<em>60 - 13 = 47 inches</em>
<em />
To find your area, you would multiply both of your factors (length and width) together.
<em> 60 x 47 = 2,820</em>
<em />
And those are your answers!
Area = Base*Height so Base = Area/Height = 39.2/5.6 = 7 units.
To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical.
