Answer:
Area = A = 2784
Step-by-step explanation:
Let,
length of a rectangular garden = l
width of a rectangular garden = w
Given Data:
Perimeter = 212 feet
According to given condition
l = w+10
To find out:
Area = A = ?
Formula:
P=2(l+w)
Area = A = l×w
Solution:
P=2(l+w)
212 = 2(w+10+w)
212 = 2(10+2w)
212 = 20+4w
212 - 20 = 4w
w = 192/4
w = 48 feet
l = w+10
l = 48 + 10
l = 58 feet
Area = A = l×w
Area = A = 58×48
Area = A = 2784
