Solution:
<u>We know that:</u>
- Perimeter of rectangle = 2L + 2B
<u>Given:</u>
<em>Substitute the values into the expression to find the perimeter.</em>
- Perimeter of rectangle = 2L + 2B
- => 2(9) + 2(5)
- => 18 + 10
- => 28 cm
The area is found by multiplying the length by the width.
The original area = 60 x 40 = 2,400 square feet
He wants to make it 1/2 that size, so the new size would be 2,400 / 2 = 1,200 square feet.
To find the length divide the new area by the new width:
1,200 / 30 = 40
The new length should be 40 feet.
