Step-by-step explanation:

very simple yse the formula 2 (l+b) then yo will get the answer

Answer 2

Step-by-step explanation:

length = 5(1/4)m = 21/4 m

breadth = 1(1/7)m = 8/7 m

area of rectangle = l×b

= 21/4 × 8/7

= 6 m^2

&

perimeter = 2(l+b)

= 2 (21/4 +8/7)

= 2( 147+32)/28

= 179/14

= 12(11/14) m
