Question

length and breadth of rectangle is 7.5 and 2.1 cm find its area and perimeter

Answer 1

first we have formula

2×(length+breath)

2×(7.5+2.1)

2×9.6

19.2

Answer 2

l = 7.5 cm

b = 2.1 cm

Area of rectangle

= l × b

= 7.5 × 2.1

= 15.75 sq. cm

perimeter of rectangle

= 2 ( l + b )

= 2 ( 7.5 +2.1)

= 2 × 9.6

=19.2 cm
