Question

help me to find the missing measurement

Answer 1

Answer:

Step-by-step explanation:

Perimeter is 165 cm

missing measurement is suppose x

So , x + 40 + 60 + 20 + 25 = 165

so x + 145 = 165

so 145 is positive,

while shifting it on right side it becomes negative

so x = 165 - 145

So x = 20

ANS = missing measurement is 20 cm
