X - unit of length
w,l - the sides of a rectangle
7 : 2 ⇒ 7x : 2x
Perimeter: P = 207cm
Perimeter: P = 2w + 2l
therefore: 2w + 2l = 207 |divide both sides by 2
w + l = 103.5 (cm)
w : l = 7 : 2 ⇒ w : l = 7x : 2x ⇒ w = 7x; l = 2x
subtitute
7x + 2x = 103.5
9x = 103.5 |divide both sides by 9
x = 11.5 (cm)
7x = 7 · 11.5cm = 80.5cm
2x = 2 · 11.5cm = 23cm
w = 80.5cm; l = 23cm
Area = wl
Area: A = 80.5cm · 23cm = 1851.5cm²
Answer:
the correct answer is a because it shows more evidence for itnn
Step-by-step explanation:
and the explanation for this question is that it's really simple and easy.
Answer:
the right answer is rectangle
Step-by-step explanation:
Compare the pairs of sides. One pair measures 4 inches, but the other pair does not and forms 90 ° angles. This figure does not have its four congruent sides, so it is a rectangle.
Answer: $525
Step-by-step explanation:
The formula for Simple interest is calculated as PRT where
P = Principal = $7500
R = Rate = 3.5%
T = Time = 2 years
Interest = PRT
= 7500 × 3.5% × 2
= 7500 × 0.035 × 2
= $525
First draw a line in the middle of your box vertically. Then draw a horizontal line that is also in the middle of your box and then draw another line above the horizontal line and below the horizontal line in between the two boxes you made I added a picture below to show. The fraction is 1/8
