Question

the perimeter of a rectangle 310m the lenght is 25m greater than the width what are the length and width of a rectangle

Answer 1

Let x be the width.

length is 25m greater than the width, hence, x+25 will represent the length.

perimeter is 310m

W=x

L= x+25

Solution:

P=2(L+w)

310m=2[(x+25m)+x)]

combine like terms

310m=2(2x+25m)

310m=4x+50m

transpose

310m-50m=4x

260m=4x

divide both sides by 4

65 = x

now that we have the measurement of the width. get the measurement of the length

Length= x+25m

L=65m+25m

L=90m
