This question answer is 10 m
Answers
Step-by-step explanation:
given the perimeter of square = 48 m
the formula for perimeter of square = 4 x side
4 x side = 48 m
side = 48/4
side of square = 12 m
given perimeter of rectangle = 48
formula of perimeter of rectangle = 2( l + b)
2( l + b ) = 48
l + b = 48 /2
l + b = 24
now its.given that the difference between their area is 4m2 , first we find the area of square and rectangle.
area of square = side x side
12 x 12.= 144m2
area of rectangle = l x b
since we don't know the values of l and b we take the area as l x b
so , we form a equation
144 - ( l x b) = 4 ( this was given in the question)
144 - lb = 4
-lb = 4 - 144
-lb = -140
lb = 140
now we have
l + b = 24 and l x b = 140
now we have to find the values of l and b. which give 24 in addition and 140 when multiplied. which is 14 and 10 m
hence the answer is 10 m
