Respuesta :

Answer:

Step-by-step explanation:

The area of the rectangular field given the dimensions of the field is 5000m^2.

What are the equations that can be used to determine the dimensions of the field?

a + b = 150 equation 1

a = 2b equation 2

Where:

a = length

b = width

Whats the width?

Subsiture for b in equation 1 using equation 2

2b + b = 150

3b = 150

b = 50m

What is the length?

a = 2 x 50

q = 100m

What is the area of the field?

Area = length x width

100 x 50 = 5000 m^2
