Answer:
D. 266 yards²
Explanation:
First, we find the area of the 2 rectangles:
Area of square = L x W
L = 6 yd
W = 7 yd
(6 x 7) x 2 = 84 yd²
Second, we find the area of the 2 side rectangles:
Area of rectangle = L x W
L = 7yd
W = 7 yd
(7 x 7) x 2 = 98 yd²
Finally, we find the area of the top and bottom rectangles:
Area of rectangle = L x W
L = 7 yd
W = 6 yd
(7 x 6) x 2 = 84 yd²
Find the surface area by adding all the areas together:
84 + 98 + 84 = 266 yards²
So, the answer is D. 266 yards².
