Question

A rectangle has a length given by 2x -1 units, where x is a variable. The width of the rectangle is equal to 3 units. Find the value of x if the area of the rectangle is equal to 27 square units.

Answer 1

Step-by-step explanation:

Given,

length=2x-1 units

breadth= 3 units

area= 27square units

We know,

Area=length×breadth

27=(2x-1)×3

27=6x-3

6x=27+3

x=30÷6

x=5 units

Length=2x-1=2×5-1=10-1=9units
