Question

A rectangular field has a perimeter of 150m. The field is 15 metres
longer than it is wide. The width of the field is x metres.
(a) Write down an equation for this information.
(b) Solve your equation to find the width of the field
(c) Find the length of the field

Answer 1

Answer:

(a) 150 = 2(x+x+15)

(b) Width = 60 m

(c) Length = 75m

Step-by-step explanation:

Perimeter = 150 m

Width = x

Length = x+15

Perimeter of rectangle = 2(l+b)

(a) 150 = 2(x+x+15)

    75 = x+15

     x = 60m

(b) Width = 60 m

(c) Length = x + 15 = 60+15 = 75m
