LESSON 4: OPENER
The Smithville City Council has decided to build a new recreation center. The city
has already purchased a 450-foot by 600-foot lot on which to construct the
recreation center. A plan of the lot is shown here.
1. What is the perimeter of the lot?
2. What is the area of the lot?
A = total squares in the figure
Ar = Area of a rectangle
Ar = length times width
P= the distance around
= twice the length + twice the width
= 21 + 2w
or
Recreation Center
or
= twice the base + twice the hight
= 2b + 2w
Ar = lw
Ar = base times hight
Ar = bh
