Well, darling, the area of a rectangle is calculated by multiplying the length by the width. So for a rectangle that's 3 yards by 5 yards, you simply multiply 3 by 5 to get an area of 15 square yards. Voila, math made fabulous!

Answer: 30 yards. Explanation: let's say it is L yards long and W yards wide. Then perimeter is 2L+2W The area is LxW=50 So Since LW=50, we substitute L=2W and write 2W(W)=2W^2=50. so W^2=50/2=25 and W=5 Now 2W=10 which is L So is it 10 yards long and 5 yards wide Let's check that. Area is 10x5=50 as desired and Length is 10 which is twice 5 as desired Now perimeter is 2L+2W=2(10)+2(5)=20+10=30 yards.
The area of rectangle is : 20.0
Volume=1/3(Base x height) 1/3(18x5)=30 yards^3
