Question

The area of a rectangle is 45cm and its length is7 cm then
Find the perimeter of rectangle​

Answer 1

apply the formulae of perimeter

Answer 2

Given:-

Length=7cm

Let breadth be xcm.

Area of rectangle= 45cm

= l × b = 45cm

= 7×b = 45cm

= b = 45÷7

= b = 6.4cm

hence,

perimeter = 2×(l+b)

= 2×(7+6.4)

= 2×13.4

= 26.8cm
