A football field measures 100m by 72m . A school marks a football field similar in shape to a full size football field but only 30m long . What is its width ?

240 m

Step-by-step explanation:

Given

Football field measures

Another similar field of length

and width, say W is marked

So, their area must be the same

the football field is similar to the other so the ratio of the corresponding sides are equal

Step-by-step explanation:

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)
