The perimeter of a rectangle is 88 m. if the width were doubled and the length were increased by 12 m, the perimeter would be 152 m. what is the length of the original rectangle?

24 meters.

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

Where l is the lenght and w is the width.

The perimeter of the original rectangle  is 88 m, then:

     [EQUATION 1]

Where l is the length of the original rectangle

 You know that if the width were doubled and the length were increased by 12 m, the perimeter would be 152 m. Therefore the new length is:

The new width is:

Susbtitute into the equation of the perimeter and solve for w:

       [EQUATION 2]

Substitute the Equation 2 into Equation 1 and solve for the length, as you can see below:

Therefore, the length of the original rectangle is 24 m.

Length  of original rectangle = 24 m

Step-by-step explanation:

Perimeter of rectangle

P = 2(l + b)

l - length and b - width

It is given that,the perimeter of a rectangle is 88 m. If the width were doubled and the length were increased by 12 m, the perimeter would be 152 m

Perimeter of original rectangle = 88 m

2(l + b) = 88

l + b = 44

b = 44 - l

To find length and width

length l = l + 12  and width = 2(44 - l) then,

Perimeter = 152 m

we can write,

2( l + 12 + 2(44 - l)) = 152

l + 12 + 88 - 2l = 152/2 = 76

100 - l = 76

l = 100 - 76 = 24

Therefore length = 24 m

width = 44 - l = 44 - 24 - 20 m

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
