Answer:

1) 144 ft

2) 292.5 ft

Step-by-step explanation:

1) SA= lw+ 4(1/2( <em>l </em>)h)

SA=6*6+ 4(1/2( 6 )9)

SA=36+ 4(1/2( 6 )9)

SA=36+ 4( 3*9 )

SA=36+ 4( 27 )

SA=36+ 144

2) SA= 1/2( / )h+ 3(1/2( <em>l </em>)h)

SA=1/2( 15 )13+ 3(1/2( 10 )13)

SA=7.5*13+ 3 ( 5*13 )

SA=7.5*13+ 3 ( 65 )

SA= 97.5+ 3 ( 65 )

SA=97.5+ 195

SA= 292.5

Write a function rule for the area of rectangle whose length is 2ft more than its width. What is the area of the rectangle when

Marianna [84]

According to the problem, the length is 2 feet more than its width, which is expressed as the following function

$l=w+2$

If the width is x, then the length is x+2.

We can express the following function for the area

$A(x)=x(x+2)$

Let's replace the width x = 11 ft.

$A(11)=11\cdot(11+2)=11(13)=143$ <h2>Hence, the area is 143 square feet. </h2><h2>The function for the area is</h2> $A(x)=x(x+2)$

Where x represents the width.
