Answer:

Step-by-step explanation:

1) we have to find the area of the cut out portion

Since both circles in one side makes up the side 28cm

The diameter of each circle is 14cm

radius = diameter / 2

r = 7cm

Area of a circle = πr²

A = 22/7 × 7²

= 22/7 × 7 × 7

= 22 × 7 = 154cm²

So the four circles will make

= 154 + 154 + 154 + 154

= 616 cm²

The Area of the square will be

= L × L

= 28 × 28

= 784 cm²

Therefore the area of the remaining portion will be

Area of the square - total area of the circles

= 784 cm² - 616 cm²

= 168 cm²

The area of the remaining part is 168 cm²

Answer:

168 cm²

Step-by-step explanation:

square- 4circles

Area of square = 28² = 784

Radius of circle = 28/4 = 7

Area of 4 circles = 4[(22/7)×7²)] = 616

Shaded area = 784-616 = 168 cm²

Six plus x minus two x equals five
AleksandrR [38]

The "plus x minus two x" part basically means "minus x".

So, "six minux x equals five".

This means that six minus five is x. So, x is one!

Now, let's check this in the problem: replace x with 1. Six plus one minus two ones equals five? Yes, it does!

The answer is x=1.
