Question

Select the dimensions of a rectangle with a perimeter of 50 inches

Answer 1

length = 21 inches

Explanation:

Missing information

In this question some information is missing the width is not given in the question .The width in this question is 4 inches we have to find the length of the rectangle .

We know that the perimeter of rectangle is given as

`p=2w+2l`........................equation(1)

where p=perimeter

w= width

l= length

Now putting the value of width and perimeter in the equation(1) we get ,

`50=2(4)+2l`

50=8+2l

50-8=2l

42=2l

`l\ =\ (42)/(2)\ \\ l\ =21\ inches`

Therefore length of the dimension is 21 inches
