find the breath of the rectangle whose perimeter is 168m and length is 45.5
KashishTaank:
perimeter of rectangle is given = 168. and length = 45.5. perimeter of rectangle is 2(l+b). 2 multiply by 45.5+b=168. then 91.0+b = 168. b = 168-91= 57 ans
its wrong
Ohh sorry

We are given, l = 45.5 m
Let Breadth be b
We are given, 2(l+b) = 168
so, l+b = 84
45.5 + b = 84
so, b, Breadth = 84-45.5 = 38.5 m
Let Breadth be b
We are given, 2(l+b) = 168
so, l+b = 84
45.5 + b = 84
so, b, Breadth = 84-45.5 = 38.5 m

perimeter=2(l+b)
=168=2(45.5+b)
=168=91+2b
=b=168-91/2
=77/2
=38.5 cm
=168=2(45.5+b)
=168=91+2b
=b=168-91/2
=77/2
=38.5 cm
