Question

a rectangle measures 2(3x-1)cm by (2x+3)cm if its perimeter is 98cm,what are the dimensions of this rectangle

Answer 1

Answer:

So the dimensions are 2(3x-1) =6x-2

And 2x+3

Step-by-step explanation:

Now, perimeter =2(l+b)

98cm=2(6x-2+2x+3)

98=2(8x+1)

98=16x+2

96=16x

x=96/16

x=6cm

So, dimensions = 6x-2=36-2=34cm

=2x+3=15cm

Answer 2

Answer:

perimeter =2(l+b)

98=2(6x-2+2x+3)

2(8x+1)=98

8x+1=98/2

8x+1=49

8x=49-1

8x=48

x=48/8

x=6

l=(6*6-1)

=36-1

=35

b=(2*6+3)

=(12+3)

=15
