The perimeter of a rectangle is 30 cm and its length is x cm. Find its area in terms of x. step by step explanation.

mars1129 [50]

Answer:

The area of the rectangle in terms of 'x' = 13x

Step-by-step explanation:

Perimeter = 30 cm

Length = x cm

Using the perimeter formula to find the width w.

$P=2(l+w)$

$P = 2l + 2w$

$2w = P-2l$

Dividing both sides by 2

$w\:=\:\frac{P}{2}-2$

as P = 30 cm

$w\:=\:\frac{30}{2}-2$

$w\:=\:15-2$

$w = 13$ cm

Using the formula of the rectangle area

$A = wl$

substitute w = 13 and l = x in the formula

$A=13\times \:x$

$A = 13x$

Therefore, the area of the rectangle in terms of 'x' = 13x

A gallon of Moo Milk cost $5.12. What is the price, in dollars, of an 8 oz glassof Moo Milk?

MA_775_DIABLO [31]

The cost for a gallon of Moo Milk is $5.12
To find the cost of 8 fl. oz. of Moo Milk, the unit price must be found.

Therefore:

One gallon of liquid equals 128 fluid ounces.

5.12 ÷ 128 = 0.04

0.04 × 8 = 0.32

Therefore, the cost of 8 fluid ounces of Moo Milk is $0.032

I hope this helped - Maria S.
