The General Case: Seeking The Area of A Shaded Region
Given: Rectangle
L2 = 15 m
W2 = 8 m
x = y = a = b = 1 m
Check that all units are uniform, convert to common unit of measurement
A1 = Area of Exterior Rectangle
A2= Area of Interior Rectangle
alif = area of the shaded region
Seek alif
A1 = A2 + alif
alif = A1 - A2 ==>
=L1*W1 - L2*W2
=[(a + L2 + b) *(x + W2 +y)] -L2W2
=[(1 +15 + 1) (1+ 8 +1)]-[(15)*(8)]
=170 - 120
= 50 m²
Answer:
50
Step-by-step explanation:
Area of pool = (l x b) = (15 x 8) = 120
Area of pool + path = (17 x 10) = 170
Area of path = 170 - 120 = 50
