Answer:

The compound inequality:

30 ≤ 2L + 2w ≤ 64

w < 12

The range:

3 ≤ w < 12

Step-by-step explanation:

Let L be he length , w the width and p the perimeter

p=2L + 2w

30 ≤ p ≤ 64 ⇌ 30 ≤ 2L + 2w ≤ 64 ⇌ 30 ≤ 24 + 2w ≤ 64 ⇌ 6 ≤ 2w ≤ 40

⇌ 3 ≤ w ≤ 20

but ,since the width is less than the length then w < 12

then 3 ≤ w < 12

The length of Albert's rectangular are listed below.
trapecia [35]
A. Length - 100 ft Width - 50 ft is the measurement of Tony's backyard.

Albert's Perimeter = 2(l+w) = 2(40+20) = 2(60) = 120 ft.

Tony's Perimeter = 120 ft * 2.5 = 300 ft
Tony's length = 40 ft * 2.5 = 100 ft
Tony's widht = 20 ft * 2.5 = 50 ft

To check tony's perimeter:
P = 2(l + w) = 2 (100 + 50) = 2 (150) = 300 ft.

Help me please and thank you
Kisachek [45]

Answer:

12.5 un^2

Step-by-step explanation:

The formula for area of a trapezoid is (a+b)/2 *h

a and b are the shorter and longer bases respectively. H is height, you have both.

Simply plug it into the equation and find your answer.

(2.5+7.5)/2 *2.5 = 5*2.5 which is equal to 12.5. Add units.
