Question

the breadth of a rectangle is 4/9 of its length . if the perimeter is 100m. find the dimensions.

Answer 1

length=x
breadth=4/9x
perimeter=100m

Perimeter=2(L+B)
2(x+4/9x)=100
2×13/9x=100
26/9x=100
x=9×100/26
×=450/13
length=450/13
breadth=450/13×4/9
200/13m


Hence,
the breadth is 200/13 m
