Question

the length of rectangle is 7.2 c.m and breadth is 2.5. what is area and perimeter

Answer 1

Length = 7.2 cm
Breadth = 2.5cm
Perimeter = 2(l+b) = 2 (7.2+2.5) = 2×9.7
=19.4cm
area = l×b = 7.2 × 2.5 =18cm^2

Answer 2

We know that in a rectangle, Opposite Sides Are Equal
{l=7.2 cm ; b=2.5cm}
Hence Perimeter = 2(l+b)
                              =2(7.2+2.5)
                              =2(9.7)
                             =19.4 cm

And Area = l*b
                 = 7.2*2.5
                 =18 cm²
