Question

for what value of x , the perimeter of this shape is 186 cm.​

Answer 1

Answer:

value of x is 3cm.

............

Answer 2

Answer:

3 is the required value of x.

Step-by-step explanation:

Explanation:

Given that, the perimeter of the given figure is 186cm.

We can see that the given figure is a rectangular shape.

So, length of the rectangle = (5x + 6)

and breadth of the rectangle = (2x + 66)

Step 1:

Perimeter of a rectangle = 2 (l + b )

We have, l = (5x + 6) and b= (2x + 66).

And given that perimeter of the given shape is 186cm

Now, from the formula

⇒2[(5x + 6)+ (2x + 66)] = 186

⇒2[7x + 72] = 186

⇒14x + 144 = 186

⇒14x = 186 - 144 = 42

⇒ x = $\frac{42}{14}$ = 3

Final answer:

Hence, 3 is the required value of x.
