Question

Type the correct answer in the box. Jason builds doghouses for a pet store. Each doghouse is a wooden structure with a rectangular base that has an area of 21 square feet and a length that is 4 feet more than its width. If x represents the width of the doghouse, write an equation in the given form that can be used to determine the possible dimensions of the base of the doghouse.

Answer 1

Answer: Our equation that can use to determine the possible dimensions of the base of doghouse is given by

$21=x\times (x+4)\\\\21=x(x+4)$

Possible dimensions would be

Length = x+4

Width = x

Step-by-step explanation:

Let the width of doghouse be 'x'.

Let the length of doghouse be 'x+4'.

Since we have given that

Area of doghouse = 21 sq. feet

As we know the formula for "Area of rectangular base = Length × Breadth":

So, Our equation that can use to determine the possible dimensions of the base of doghouse is given by

$21=x\times (x+4)\\\\21=x(x+4)$

Possible dimensions would be

Length = x+4

Width = x

Answer 2

Answer:

x(x + 4) = 21

Step-by-step explanation:

Area = length * width.

21 = x + 4  *  x

x(x + 4) = 21
