A rectangular playground has an area of 3,392 square meters. if the width of the rectangle is 32 meters.find the lenth
2 answers:
The length of the rectangle is 106 meters.
<h3>Further explanation </h3>A rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, because equiangular means that all of its angles are equal. A rectangle can also be defined as a parallelogram containing a right angle.
Whereas the square metre (or square meter) is the SI derived unit of area thar has a symbol sq.m
Length is describes how long something is, while width is describing how wide an object is. It also defined that length pertains to the longest side of the rectangle while width is the shorter side
A rectangular playground has an area of 3,392 square meters. If the width of the rectangle is 32 meters, find the length.
By dividing area of rectangular playground by the width of the rectangle we get:

The perimeter of the shaded part is 3.93 cm.
Step-by-step explanation:
Step 1; The perimeter of a circle is calculated by multiply 2π with the radius. This given circle is not an entire circle. An entire circle has an angle if 360° while this has an angle of 50°. So we divide 360° with 50°.
Number of these shapes to form a full circle = 360° / 50° = 7.2. So 7.2 of these shapes will need to be combined to form a full circle. So we can calculate the perimeters of full circles and then divide it by 7.2 to get the parameters of the given sections.
Step 2; The parameter and circumference of a circle are equal. So
The perimeter of shaded region = Perimeter of the entire region - Perimeter of the unshaded region.
The Perimeter of circle with radius 8cm = 2π × 8 = 50.2654 cm.
The perimeter of the given shape = = 6.9813 cm
The perimeter of circle with radius, 3.5cm (8cm - 4.5cm) = 2π × 3.5 = 21.9911 cm,
The perimeter of unshaded region = = 3.0543 cm.
So the perimeter of shaded region = 6.9813 cm - 3.0543 cm = 3.927 cm.
Rounding 3.927 to 3 significant figures we get the perimeter of shaded region equal to 3.93 cm.
