Question 1
The side without a measurement can be calculated by subtracting 19𝑐𝑚 from 25𝑐𝑚 to get 6𝑐𝑚
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 = 𝑙𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑎𝑙𝑙 𝑠𝑖𝑑𝑒𝑠
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 = 5 𝑐𝑚 + 19 𝑐𝑚 + 13 𝑐𝑚 + 6 𝑐𝑚 + 18 𝑐𝑚 + 25 𝑐𝑚
= 86 𝑐𝑚


Question 2


𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 𝑜𝑓 𝑎 𝑟𝑒𝑐𝑡𝑎𝑛𝑔𝑙𝑒 = 2𝑙 + 2𝑤
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 𝑜𝑓 𝑟𝑒𝑐𝑡𝑎𝑛𝑔𝑙𝑒 = 2 × 16 𝑚 + 2 × 4 𝑚
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 𝑜𝑓 𝑟𝑒𝑐𝑡𝑎𝑛𝑔𝑙𝑒 = 32 𝑚 + 8 𝑚 = 40 𝑚


Question 3
To get the length of the top and bottom part of the gray shaded figure. We subtract
2 × 6 𝑐𝑚 from the length of the large rectangle, i.e., 19 𝑐𝑚 to get 7 𝑐𝑚.
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 = 𝑙𝑒𝑛𝑔𝑡ℎ 𝑜𝑓 𝑎𝑙𝑙 𝑠𝑖𝑑𝑒𝑠
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 = 5 𝑐𝑚 + 7 𝑐𝑚 + 6.5 𝑐𝑚 + 6.5 𝑐𝑚 + 7 𝑐𝑚
𝑃𝑒𝑟𝑖𝑚𝑒𝑡𝑒𝑟 = 32 𝑐𝑚
