Answer:

LENGTH= <em>1</em><em>6</em><em> </em><em>and</em><em> </em><em>WIDTH</em><em>=</em><em> </em><em>1</em><em>3</em>

Step-by-step explanation:

Let the length of rectangle be l

and, its width be b

So, according to question

l = b+3

and,

2(l+b)=58

[We know that perimeter of a rectangle= <em><u>2</u></em><em><u>(</u></em><em><u>l</u></em><em><u>+</u></em><em><u>b</u></em><em><u>)</u></em><em><u>]</u></em>

Substituting l=b+3 in 2nd equation

2(b+3+b)=58

2b+3=58/2

2b+3=29

2b=29-3=26

b=26/2

b= 13

So, l=b+3

l= 13+3=16

Hence the dimensions are 16 and 13

A rectangle with a length of 6 inches and a width of 1 foot has a perimeter of 14 inches.
Pachacha [2.7K]
The length is 6 inches.
The width is 1 foot = 12 inches.

The perimeter is  (6 + 12 + 6 + 12) = 36 inches (3 feet) .

"14 inches" is false.

1. When you measure the length of an object to the eighth of an inch and again to the fourth of an inch, which measurement is mo
sladkih [1.3K]

Answer:

The eighth of an inch scale measures more precisely.

Step-by-step explanation:

An eighth of an inch means that one inch is divided into 8 equal lengths on the scale i.e. the minimum length that can be measured is \frac{1}{8} =0.125 inch.

Again a fourth of an inch means that one inch is divided into 4 equal lengths on the scale i.e. the minimum length that can be measured is \frac{1}{4} =0.25 inch.

Therefore, the eighth of an inch scale measures more precisely as it can measure more small measurements. (Answer)
