Question

Roshni's rectangular quilt has an area of 12 sq m. One side is 3 m long. (1) What is the length of the other side? (ii) What is the perimeter of the quilt? ​

Answer 1

Answer:

i) 4m

ii) 14m

Step-by-step explanation:

The area of the rectangular quilt =12m²

One side of the rectangle is 3m.

Let the given side be b and the other side be l

So, b=3m

Now, area=l×b

or, 12= l×3

or, l=4m

So the other side of the rectangle is 4m

Perimeter =2×(l+b)

=2×(3+4)

=2×7

=14m

Hence, the perimeter of the rectangular quilt is 14m
