Question

A square is divided into three congruent rectangles as shown at the right. Each of the three rectangles has a perimeter of 16 meters. How many meters are in the perimeter of the square?

Answer 1

Perimeter of square = 24 meter

Explanation:

Given:

Square divided into three equal rectangle

Perimeter of rectangle = 16 meter

Find:

Perimeter of square

Computation:

We know that rectangle are equal

So,

3b = l

Perimeter of rectangle = 2 (l + b)

16 = 2 (l + b)

16 = 2 (3b + b)

b = 2 meter

l = 3 (2) = 6 meter

Side of square = 6 meter

Perimeter of square = 4(side)

Perimeter of square = 4(6)

Perimeter of square = 24 meter
