Answer:
30
Step-by-step explanation:
Step 1: Find the area of the whole figure
The whole figure is a rectangle with a width of 4cm and a length of 12cm
The area of a rectangle can simply be calculated by multiplying the width by the length
So area = 4 * 12 which = 48
So the area of the whole figure is 48cm²
Step 2: Find the area of the non shaded area
The non shaded area forms a triangle with a base length of 9cm and a height of 4cm
The area of a triangle can be calculated using this formula
where b = base length and h = height
That being said we plug in the values into the formula
Hence the area of the non shaded region is 18cm²
Final step: Our last step is to subtract the area of the non shaded region by the area of the whole figure
so the answer = 48 - 18 which equals 30
Hence the area of the shaded region is 30 square centimeters.
The answer to the question is null set
Answer:
Perimeter of rectangle = 140 cm.
Step-by-step explanation:
As we know that,
Rectangle is defined as a quadrilateral having opposite sides are equal and each angle are at 90°.
Let the length of rectangle = l
And the width = b
Therefore,
Perimeter of rectangle is given by = 2 (l × b)
From the question,
Given:
length = l = 17.5 cm
Width = b = 40 mm = 4 cm
( because 1 cm = 10 mm)
Perimeter of rectangle is given by = 2 (l × b) = 2(17.5 × 4) = 140 cm.
Hence, the perimeter of rectangle = 140 cm.
Square root of 6 times 16 will give us 39.19
The square root of 48 times 32 [which gives us 1536] is also equal to 39.19
The square root of 1536 is equal to 39.19
Hence, x is equal to 32
