Question

A rectangle has a perimeter of 22 m and a width of 4 m. What is the length of this rectangle in meters?

a) 3 m
b) 5 m
c) 7 m
d) 9 m

Answer 1

To find the length of the rectangle, use the formula for the perimeter of a rectangle, which is 2 times the length plus 2 times the width. Plug in the given values and solve for L.

Step-by-step explanation:

To find the length of the rectangle, we need to use the formula for the perimeter of a rectangle, which is 2 times the length plus 2 times the width.

Given that the perimeter is 22 m and the width is 4 m, we can plug these values into the formula:

22 m = 2L + 2(4 m)

Now we can solve for L:

22 m = 2L + 8 m

Subtracting 8 m from both sides:

14 m = 2L

Dividing by 2:

L = 7 m

Therefore, the length of the rectangle is 7 m.
