Answer:
The correct answer is perimeter is given by 2 × ( l + w), where l is the length and w is the width of the rectangle.
Step-by-step explanation:
A rectangle has a length of 6 feet and a width of 4 feet. The perimeter of the rectangle can be found using the equation =2×6+2×4.
Let l be the length and w be the width of a rectangle.
Since there four sides of a rectangle, the perimeter is given by adding all the sides.
Therefore perimeter of the rectangle is given by l + l + b + b = 2×l +2×w = 2 × ( l + w).
The equation given by 2 × ( l + w) can also be used to find the perimeter of any given rectangle.

Step-by-step explanation:
∠A = ∠E (same arc BD)
∠X share
ΔXDA similar to ΔXBE
XE / XA = XB / XD
(3 + DE) / 9 = 2 / 3
9 + 3DE = 18
3DE = 9
DE = 3
Answer: 20 students mow on Saturday, 3 of those sleep until noon. Those who don’t mow the lawns, 21 of them sleep until noon.
Step-by-step explanation: 40% of 50 is 20. 25% of 20 is 3. 50-20=30. 70% of 30 is 21
