Question

(a) The perimeter of a rectangular field is 350 m.

If the width of the field is 79 m, what is its length?

Answer 1

Answer: 96 m.

Step-by-step explanation: Let's call the length of the rectangular field "L".

We know the perimeter of the field is equal to the sum of all its sides, so:

350 = 2L + 2 * 79

Expanding the right side, we have:

350 = 2L + 158

Subtracting 158 from both sides:

192 = 2L

Dividing both sides by 2:

L = 96 m

So the length of the rectangular field is 96 m.
