Question

A hopscotch is formed by the same size of rectangles as shown. If the perimeter of this structure is 110 units. What is the value of 'k'?

• A. 6

Answer 1

The correct option is A 6
Given

The Perimeter of the hopscotch = 110 units

Perimeter of the hopscotch = Add length 10 times and width 10 times

10 times length = 10 $\times$length = 10 $\times$ k = 10k units

10 times width = 10 $\times$width = 10 $\times$ 5 = 50 units

Perimeter = 10k + 50

110 = 50 + 10k

110 - 50 = 10k

60 = 10k

k = 6

Therefore, the value of 'k' is 6.
