Question

If the perimeter of the given rectangle is 50 m, what will be its length?

Answer 1

We know that the measure of opposite sides of a rectangle are equal.
So, the measure of side opposite to 6 m will also be 6 m.

Perimeter of the rectangle = 6 + length + 6 + length
Given, Perimeter of the rectangle = 50 m
So, 6 + length + 6 + length = 50 m
12 + 2 $\times$ length = 50 m
2 $\times$ length = 38 m
Therefore, length = 19 m

The length of the given rectangle is 19 m.
