Answer:
<h2>
7m x 4m</h2>
Step-by-step explanation:
Area of a rectangle (A) = L * W -----1
Perimeter (P) = 2L + 2W ----------2
where:
A = 28 sq. m.
P = 22 m.
we can use either formula 1 or 2 to get L or W
say
A = L * W
28 = L * W
L = 28 / W
substitute L = 28 / W into formula 2
P = 2L + 2W
22 = 2(28 / W) + 2W then multiply W on each side
22W = 56 + 2W²
solve W using quadratic equation:
W = 7 and W = 4
therefore
the dimension of the garden is: 7m x 4m
