Question

Chapter 3, Problem 36CP

To determine

To find:the value of x

Expert Solution & Answer

Answer to Problem 36CP

The value of x is x=1 .

Explanation of Solution

Given information:

The area of rectangle is 28 square unit and length is (3x+4) unit and breadth is 4 unit.

Formula used:

The area of rectangle,

P=l⋅b [where l is length and b is breadth and p is area]

Calculation:

Use formula of perimeter of rectangle,

P=l⋅b

Substitute P=28,l=3x+4 and b=4

28=(3x+4)⋅428=12x+16 [distributive property]28−16=12x [group like terms]12=12x [substract]1212=x [cross multiply]1=x [divide]

Hence, the value of x is x=1 .
