We will assume Jen's garden is rectangular.
Take the formula for the area of a rectangle, where [tex]A[/tex] is the area, [tex]l[/tex] is the length, and [tex]w[/tex] is the width.
[tex]A=lw[/tex]
Substitute in the known values.
[tex]28=l4\to28=4l[/tex]
Divide both sides by [tex]4[/tex].
[tex]\boxed{7}=w[/tex]
Given:
- Wide ( breadth) = 4 feet
- Area of given rectangle = 28 ft²
To find out:
What is the length of jens garden?
Formula used:
Area of rectangle = Length × Breadth
Solution:
Let the length be l .
⋆ According to question:-
[tex] \sf \purple{Area \: of \: rec. = Length \times Breadth }[/tex]
Substituting the values of breadth and area of rectangle.
[tex]: \implies28 = l \times 4[/tex]
[tex]: \implies \: l = \cancel \frac {28}{4} [/tex]
[tex]: \implies \sf \bold{ l = 7 \: feet}[/tex]
Hence, The length of given rectangle is 7 feet .
