Question

the length and breadth of a rectangle are 7.1 cm and 2.5 cm respectively. find its perimeter and area .

Answer 1

Length = 7.1 cm
Breadth = 2.5 cm
So perimeter = $2\left(\mathrm{length}+\mathrm{breadth}\right)=2\left(7.1+2.5\right)=2\times 9.6=19.2\mathrm{cm}$
And area = $\mathrm{length}\times \mathrm{breadth}=7.1\times 2.5=17.75{\mathrm{cm}}^2$
