Answer:  The length is 510 and the width is 110. 
Step-by-step explanation:
To find the area of a rectangle, you will have to add the 2 times the length plus 2 times the width because  a rectangle have 4 sides. Two widths and two  lengths. 
You can now use the formula  P= 2l + 2w  
were P is the perimeter , l is the length, and w is the width. 
the length is 400 more than the width, so we can represent that by the equation,  l = w + 400   
And now we know that the width is w. 
So now we will input the perimeter, length, and into the formula to solve for w. 
1240 = 2(w + 400) + 2w 
1240 = 2w + 800 + 2w 
1240 = 4w + 800 
-800            -800 
    440 = 4w 
     w = 110
L= 110 + 400 
L = 510  
Check : 
1240 = 2(510) + 2(110) 
1240 = 1020 + 220 
1240 = 1240
 
        
             
        
        
        
Answer:
256
Step-by-step explanation:
First, handle the exponent:
2²=4 (2*2=4)     and     4³=64 (4*4=16*4=64)
Now multiply those two outcomes:
4*64=<u>256</u>
This equation is also known as 4⁴
 
        
             
        
        
        
Answer:
36 in²
Step-by-step explanation:
The figure that is been described is a Parallelogram.
The area of a Parallelogram is = Base × Height
From the question, the Height of the Parallelogram = 4 inches
The Base of the Parallelogram is calculated as the Length or base of the rectangle + base of the triangle
= 5 inches + 4 inches
= 9 inches
Area of the Parallelogram = 9 inches × 4 inches
= 36 square inches or 36 in²
