Question

write a function rule for the area of a rectangle whose length is 4 in more than its width what is the area of the rectangle when it's width is 8 in

Answer 1

Answer: Function rule: F(L)=4L+8 Area: 96

Step-by-step explanation: Basically, if the length is 4 more than the width, that means the length is 12. Now, to get area you multiply length times width. So, 12 times 8 equals 96.

Hope this helps :)

Answer 2

The function rule for the area of a rectangle is F(L) =4L+8.

The area of the rectangle is 96 square inches.

Given that,

The area of a rectangle whose length is 4 in more than its width.

We have to determine,

Write a function rule and what is the area of the rectangle when its width is 8 in.

According to the question,

The area of a rectangle whose length is 4 in more than its width.

Then,

The width of the rectangle = 8 in

And the length of the rectangle = 8 + 4 = 12 in

Therefore, The area of the rectangle = length  × width  

The area of the rectangle = 12 × 8 = 96 square inches

And the function rule: F(L) = 4L+8.

Hence, the function rule: F(L)=4L+8.

The area of the rectangle is 96 square inches.
