Question

the Length and width of a rectangle are in the ratio 5 is to 3 find the dimension of the rectangle if its perimeter is 112 CM​

Answer 1

Answer:

let the common ratio be x

therefore,

length(l)=5x

width or breadth(b)=3x

perimeter=112cm

B.T.P

2(l+b)=112

or,2(5x+3x)=112

or,8x=112/2

or,x=56/8

or,x=7

therefore,

length=5x=5×7=35cm

width=3x=3×7=21cm
