Question

1.
The length of a rectangle is 1 cm more than its width and its perimeter is 14 cm. Then the zenia) Thea
rectangle is
a) 16 cm
b) 12 cm
c) 48.75 cm
d) 10 cm​

Answer 1

Answer:

Correct option is

C

12cm

2

Let the width of the rectangle be w

Since, the length of the rectangle l=w+1

Since, the perimeter of the rectangle

2(l+w)=14

(w+1+w)=7

2w=6

w=3 cm

And l=3+1=4 cm

We know that area of the rectangle will be

=l×w

=4×3

=12 cm

2

Hence, this is the answer.

Answer 2

Answer:

b) 12 cm

Step-by-step explanation:

2(l+b)=perimeter

2(x+x+1)=14

2x+2x+2=14

4x+2=14

4x=14-2=12

x=2÷4

x=3

width = 3cm, length=(3+1=4cm) area = 3×4=12cm.

this is answer.
