For this case we must solve the following equation:
To solve we follow the steps below:
We square both sides of the equation squared:
We choose the positive value because we talk about $.
Answer:
$6
13. The sports field shown in the image below has a 90m by 70m football field with a semi-circular area at each end. A tract run
1 answer:
The area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.
<h3>What is the area of the rectangle?</h3>It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Area of the sports field = area of the rectangle + area of the two semicircle
Area of the sports field = 90×70 + π(70/2)²
= 6300 + (22/7)1225
= 6300 + 3850
= 10150 square meters
Length of the track = perimeter of the rectangle + circumference of the
two-semi circle
= 90 + 90 + 2π(70/2)
= 180 + 70(22/7)
= 180 + 220
= 400 meters
Thus, the area of the sports field is 10150 square meters and the length of one lap of the track is 400 meters.
