Answer:
A. length = 4yd, width = 2yd
Explanation:
Given that
The area of a playground is 50 square yards
And, the length would be 2 times the width
Here the area is 8 square yards
And, the length be 2w
where w denotes the width
Now as we know that
Area of the playground = length × width
8 = 2w × w
2w^2 = 8
Now Divide both sides by 2
So,
2w^2 ÷ 2 = 8 ÷ 2
w^2 = 4
w = 2
And, length be
= 2 × 2
= 4 yards
hence, the correct option is A.
