Question

Pinky is making a hopscotch in which all rectangles are of the same size. If the perimeter of this structure is 112 units. What is the value of 'y'?

• A. 6
• B. 5
• C. 4
• D. 2

Answer 1

The correct option is C 4

Given

The Perimeter of the hopscotch = 112 units

Perimeter of the hopscotch = Add length 12 times and width 10 times

12 times length = 12 $\times$length = 12 $\times$ 6 = 72 units

10 times width = 10 $\times$width = 10 $\times$ y = 10y units

Perimeter = 72 + 10y

112 = 72 + 10y

112 - 72 = 10y

10y = 40

y = 4

Therefore, the value of 'y' is 4.
