Question

the perimeter of a rectangular field is 360 M and its breadth is 45 M find its length

Answer 1

Perimeter of rectangle = 360m
2(l+b) = 360
l+45 = 360/2
l = 180-45 = 135m

Answer 2

Hello,
we have that:
P=2b+2h=360m and h=45 m
we calculathe the lenght of a rectangular:
2b+2(45)=360;
2b+90=360;
2b=360-90;
2b=270;
b=270÷2=135 m

The lenght of a rectangular is b=35 m

bye :-)
