<em>312 ft²</em>
- Step-by-step explanation:
<em>3 rectangles
</em>
<em>2 triangles</em>
<em>4 yd = 12 ft</em>
<em>A = 4ft×12ft + 8ft×12ft + 10ft×12ft + 2×6ft×8ft/2</em>
<em>= 48ft² + 96ft² + 120ft² + 48ft²</em>
<em>= 312 ft²</em>
Area of square/rectangle = length times width
16. 4 (9*4=36)
17. 6 (6*11=66)
18. 8 (10*8=80)
19. 9 (9*5=45)
20. 48 (4*12=48)
21. 13 (13*2=26)
Formula for volume = length × width × height
21 * 7 = 147
9 1/3 = 28/3
147 * 28 /3 = 4116/3
Simplify :
4116/3 = 1372
Volume = 1372 cm³.
Hope this helped☺☺
