Answer:

Step-by-step explanation:

ab - cd = ?

Put the numbers into the correct variables of the equation.

(5)(3) - (4)(2) = ?

Now multiply 5 and 3 with each other. This leaves you with:

15 - (4)(2) = ?

Now, multiply 4 and 2 with each other. This leaves you with:

15 - 8 = ?

Now, you are able to solve the equation.

15 - 8 = 7

Length of area = L = 1000m

Width of area = W = 400m

Distance around the rectangle = D = 2 * (L + W)

D = 2 * (400+1000)

D = 2 * 1400

D = 2800m
